A guinea contains exactly 7.7 grams of pure gold. This historic British coin's value today is primarily determined by its precious metal content, followed by its numismatic value as a collectible.
Understanding the Guinea Coin
The guinea was a significant British gold coin first introduced in 1663. It was named after the Guinea region in West Africa, from where much of the gold used for minting the coins was initially sourced. For over 150 years, the guinea served as a prominent denomination in British currency, eventually settling at a value of twenty-one shillings.

The Value of a Guinea Today
While no longer legal tender, a guinea's worth today is multifaceted, appealing to both investors and collectors:
- Metal Value: As established, a guinea contains 7.7 grams of gold. Its baseline worth is directly tied to the current market price of gold. As global gold prices fluctuate, so too does this foundational value.
- Numismatic Value: Beyond its intrinsic gold weight, a guinea coin can fetch a significantly higher price due to its rarity, historical significance, condition, and specific minting year. Collectors often seek out guineas from particular periods, those with unique features, or in pristine condition, which can considerably drive up their market value.
- Historical Significance: Guineas represent a tangible link to a pivotal era of British history, making them prized artifacts for historians and enthusiasts alike. They offer insights into the economic and social fabric of past centuries.
Why the Guinea Remains Relevant
The guinea's enduring legacy is a testament to its importance in British economic and social history. It served as the backbone for significant transactions and played a crucial role in the development of modern financial systems. Its inherent gold content provided a stable measure of wealth during periods of economic change and expansion.
Examples of Guinea's Enduring Use or Reference:
- Professional Fees: Historically, certain professional fees, such as those for medical practitioners or lawyers, were often quoted in guineas. The extra shilling (making 21 shillings instead of 20) traditionally served as a small premium or gratuity for the professional.
- Auction Sales: Even in contemporary high-end auctions, particularly for items like thoroughbred horses or fine art, prices might still be quoted in guineas. In this context, a "guinea" typically means £1.05, with the extra 5 pence (or 5% above the pound) traditionally going to the auctioneer as commission.
