Here's a Coin that tells a story. Countermarked 1861 Cartwheel Penny of 1797 St Thomas & Prince Isles Bronze.
Countermarked 1797 British "Cartwheel" pennies served several functions in colonial commerce, including local merchant advertising, weight validation for trade, and unofficial revaluation of tender. Reasons for Countermarking Cartwheel Pennies
- Merchant Advertising: Private businesses and newspapers stamped their names or logos onto heavy copper coins to leverage wide circulation.
- Shopkeeper Weights: Because a 1797 cartwheel penny weighed precisely one full ounce, merchants frequently used them as physical measurement weights and stamped their initials to claim ownership.
- Colonial Revaluation: While official colonial authorities (such as in New South Wales) occasionally proclaimed higher local values to keep heavy copper coins from being exported, private incuse countermarks often indicated localized use or identity.
- Information from Numista Webpage a very helpful page for coin information.
