Below are actual photos of some of tokens I've recovered in the United States and the United Kingdom. I have included detailed sample photos for reference if my recovered item was in rough shape. All of these are "natural" finds. I have never participated in a seeded hunt.
ENGLAND - 1780s-1790s Guinea Gaming Token.
King George III issued some gaming tokens in half guinea and guinea sizes. These coins are not to be confused with actual money, but were coins used for gaming in the same way that poker chips are used today. There are many variations on the same theme, including different metals, sizes, and designs.
ENGLAND - 1790s John Wilkinson Ironmaster Halfpenny/Token
These halfpenny/tokens are always found with the bust of John Wilkinson on the front ('obverse'), but the reverse comes in a few different versions. This version is a blacksmith facing towards the left, working at a huge anvil and furnace.
ENGLAND - 1794 Chichester Queen Elizabeth Halfpenny/Token
These halfpenny/tokens have a forward facing bust of Queen Elizabeth with crown and sceptre on the front ('obverse') and view of Chichester Cross on the back ('reverse'). PAYABLE AT DALLYS CHICHESTER is visible if you look closely at the edge of the token. Dally and Son were drapers (wholesale clothiers) in Chichester, Sussex, in south central England. Like many tradesmen of the time, they produced tokens to support commerce in their establishment.
Civil War tokens were privately minted and distributed in the United States between 1861 and 1864. They were used mainly in the Northeast and Midwest. The widespread use of the tokens was a result of the scarcity of government-issued cents during the Civil War. Civil War tokens became illegal after the United States Congress passed a law on April 22, 1864 prohibiting the issue of any one or two-cent coins, tokens or devices for use as currency. On June 8, 1864 an additional law was passed that forbade all private coinage.
