Pre-Decimal UK Coins: A Beginner’s Introduction

Before 15th February 1971, British money worked on a system that had been in use, in one form or another, for over a thousand years. Pounds, shillings, and pence — often written as £sd — formed the backbone of everyday commerce across the United Kingdom. When decimalisation arrived and replaced this system with the familiar 100-pence pound we use today, billions of old coins were withdrawn from circulation. Many were melted down. Others found their way into drawers, biscuit tins, and attic boxes, where they have quietly waited ever since.

Today, pre-decimal coins represent one of the most accessible and rewarding areas of British coin collecting. They are widely available, often inexpensive, and carry with them centuries of history — from the reigns of medieval monarchs to the post-war years of the mid-twentieth century. Whether you have inherited a handful of old pennies or you are simply curious about what those strange shillings in a car boot sale box might be worth, this guide will give you the knowledge to get started with confidence.

Understanding the Old Money System

Before you can appreciate pre-decimal coins, you need to understand the monetary system they belonged to. The pre-decimal system used three units:

The pound (£) — the largest standard unit, equal to 20 shillings
The shilling (s) — equal to 12 pence
The penny (d) — the basic unit, derived from the Latin denarius

This means that one pound contained 240 pennies. Prices were written in formats such as 2/6 (two shillings and sixpence, spoken as “two and six”) or 1/- (one shilling). There were also subdivisions of the penny, including the halfpenny (ha’penny) and the farthing (a quarter of a penny), both of which were issued well into the twentieth century.

Beyond the basic denominations, a range of coins circulated at various points in British history, including the florin (two shillings), the half-crown (two shillings and sixpence), the crown (five shillings), and the groat (four pence). Understanding these denominations helps you identify coins correctly and assess their relative rarity.

Which Coins Are Considered Pre-Decimal?

Technically, pre-decimal refers to any British coin issued before February 1971. However, most collectors focus on coins from the Victorian era onwards, as earlier coins require specialist knowledge and can be considerably more expensive. The most commonly collected pre-decimal coins include:

Farthings — last issued in 1956, withdrawn from circulation in 1960
Halfpennies — last issued in 1967
Pennies — large bronze coins, last minted in 1967
Threepenny bits — the distinctive twelve-sided brass coin, last issued in 1967
Sixpences — small silver-coloured coins, last issued in 1967
Shillings — featuring either the English lion or Scottish lion reverse depending on the year
Florins (two shillings) — introduced in 1849 as an early attempt at decimalisation
Half-crowns — popular with collectors, last issued in 1967
Crowns — large commemorative coins, produced for special occasions

Coins issued under the reigns of Queen Victoria, Edward VII, George V, Edward VIII (extremely rare), George VI, and Elizabeth II all fall within the pre-decimal period. Each reign brought distinct designs, and tracking these changes across monarchs is a fascinating aspect of building a collection.

How to Identify What You Have

When you first encounter a pre-decimal coin, the most useful information is found on both faces. The obverse (front) typically shows the reigning monarch’s portrait, along with a Latin inscription giving the monarch’s name and titles. The reverse (back) carries the denomination and a design that often changed between reigns and sometimes within a single reign.

The date is almost always present on the reverse, usually at the bottom. Mintmarks — small letters indicating where the coin was struck — occasionally appear, though most British coins were minted at the Royal Mint in London or, later, at Llantrisant in Wales. Some coins struck during wartime were produced at branch mints in countries such as Australia, India, or South Africa, and these carry their own mintmarks that can affect value significantly.

A good reference book is invaluable at this stage. The Standard Catalogue of British Coins, commonly known as Seaby or Spink after its publishers, is the standard reference used by collectors and dealers throughout the United Kingdom. Spink also publishes annual price guides that give you a solid starting point for understanding value. These books are available through Spink’s own London premises on Southampton Row, as well as through online retailers and many local libraries.

Grading: Understanding Coin Condition

Condition is everything in coin collecting. A penny from 1933 — one of the rarest British coins of the twentieth century — is worth vastly different sums depending on whether it is worn smooth or appears as if it left the mint yesterday. Collectors use a grading system to describe a coin’s state of preservation, and understanding these grades will help you buy and sell with confidence.

The main grades used in the UK are as follows, from poorest to finest:

Poor (P) — Barely identifiable. The design is almost completely worn away.
Fair (F) — Major design elements visible but heavily worn.
Good (G) — Design clear but with significant wear on all high points.
Very Good (VG) — Moderate wear, main features sharp, some finer detail lost.
Fine (F) — Light to moderate wear, most detail visible.
Very Fine (VF) — Only slight wear on the highest points, good overall definition.
Extremely Fine (EF) — Minimal wear, nearly all original detail intact.
Uncirculated (UNC) — No wear at all, as struck. May show bag marks or minor blemishes from handling at the mint.
Fleur de Coin (FDC) — Perfect in every respect, the finest possible grade.

As a beginner, you will most often encounter coins in Good to Very Fine condition. Uncirculated examples exist but command significantly higher prices. Do not be discouraged by worn coins — they are perfectly valid collectables and a worn Victorian penny is still a genuine artefact from the nineteenth century.

One important word of caution: never clean your coins. It seems counterintuitive, but cleaning a coin — even gently with a cloth — removes the natural surface patina that develops over decades and immediately reduces both its grade and its market value. Dealers can spot a cleaned coin immediately, and you will find it difficult to sell at a fair price. Leave coins exactly as you find them.

Where to Find Pre-Decimal Coins in the UK

One of the great pleasures of collecting pre-decimal coins is that they are genuinely everywhere. You do not need to spend large sums or travel to specialist fairs to build a worthwhile collection. Here are the most productive sources for UK collectors:

Car boot sales and antique markets — These are among the best hunting grounds for affordable coins. Markets such as those at Newark, Kempton Park, and Ardingly frequently turn up job lots of pre-decimal coins at very reasonable prices. The seller often has no particular knowledge of what they have, which can work in your favour — though do research prices before you go so you can recognise genuine bargains.
Charity shops — Particularly in towns with older populations, charity shops in places like Cheltenham, Bath, and market towns across the Cotswolds and Home Counties frequently receive coin collections as donations. Prices are usually very low.
Online auction platforms — eBay UK is a vast marketplace for pre-decimal coins. Search carefully, check seller feedback, and always read the description and examine photographs before bidding. Be cautious of coins listed as “rare” without supporting evidence.
Specialist coin dealers — Established dealers such as Spink & Son in London, A.H. Baldwin & Sons (also London), and Coincraft on Great Russell Street offer authenticated coins with reliable grading. Prices are higher than car boot sales, but the quality and certainty are worth it for key pieces.
Coin fairs — The largest regular UK coin fair is held at the Marriott Hotel, Regents Park, London, organised by the British Numismatic Trade Association (BNTA). Regional fairs are held throughout the country and listed on the BNTA website. These are excellent places to handle coins in person and talk with knowledgeable dealers.
Probate and house clearance sales — Collections frequently come to auction following estate settlements. Regional auction houses such as Bonhams, Dix Noonan Webb, and local county auctioneers regularly include coin lots.

Starting Your Collection: A Practical Approach

The single most common mistake new collectors make is buying randomly without a plan. A focused collection is more satisfying, easier to manage, and ultimately more valuable than a random accumulation of coins. Before you spend any money, decide on a collecting theme. Here are some sensible approaches for beginners:

One of each denomination — Collect one example of every pre-decimal denomination from a single reign, such as George VI. This gives you a coherent, manageable set.
Date runs — Pick a single denomination, such as the penny, and try to collect one coin from each year of issue. The penny was struck almost every year from the 1860s onwards, making this an achievable long-term project.
Type collecting — Collect one example of each distinct design type, regardless of date. This requires good reference material but produces a visually varied and historically informative collection.
Reign sets — Focus on one monarch’s coinage entirely. Victorian collectors often specialise further, distinguishing between the Young Head, Jubilee Head, and Old Head portrait periods.

Once you have a theme, set a realistic budget. Pre-decimal coins span an enormous price range. Common Victorian pennies in Fine condition might cost 50 pence to a few pounds each. A scarce date in Uncirculated condition could run to hundreds of pounds. As a beginner, there is no need to spend significant sums. A budget of £20 to £50 per month is more than sufficient to

When buying, you will encounter condition gradings that directly affect value. The standard scale runs from Poor and Fair at the bottom, through Good, Very Good, Fine, Very Fine, and Extremely Fine, up to Uncirculated at the top. As a beginner, Fine to Very Fine is a sensible target: coins show clear detail without the wear that makes legends and portrait features difficult to read, yet they remain affordable enough to buy in quantity. Avoid the temptation to purchase heavily worn pieces simply because they are cheap — a small collection of decent-condition coins is far more satisfying, and more valuable in the long run, than a large accumulation of worn-flat specimens. Buy from reputable dealers, established auction houses, or well-reviewed sellers on specialist platforms such as eBay’s coin category, and always check feedback carefully before committing.

Storage is an aspect beginners often overlook until damage has already been done. Never clean coins — even gentle polishing removes surface metal and destroys collector value permanently. Store coins in acid-free flips, cardboard-and-Mylar holders, or purpose-made albums with non-PVC pockets. Keep them away from damp, direct sunlight, and wide temperature fluctuations. A simple ring-binder album with individual pockets, labelled by denomination and date, costs very little and will protect your collection for decades. As your collection grows, consider a dedicated coin cabinet, which allows coins to rest flat and be viewed without handling.

Pre-decimal coinage offers a genuinely accessible route into numismatics. The coins are historically rich, visually varied, and widely available at prices that suit almost any budget. Whether you choose to focus on a single denomination, a particular reign, or the full sweep of pre-decimal currency, you will find no shortage of interesting pieces to seek out. Start small, buy carefully, learn as you go, and the collection will take shape naturally.
