Collectors often use the word “coin” broadly, but legal-tender coins, privately issued rounds and medals are not the same.
Coins
A coin is generally issued under government authority and carries a denomination or legal-tender status. Its market price can be far higher than its face value because of metal content, rarity and collector demand.
Rounds
A round is coin-shaped but is not legal tender. Private mints and brands can use rounds for bullion and limited collector designs. Specifications such as metal, weight and fineness remain central.
Medals and tokens
Medals and tokens may commemorate people, places or events. They can be made from precious or base metals, so appearance alone does not establish composition.
Collect the description, not the assumption
Read how the item is classified and verify the stated specifications. Clear terminology helps buyers understand exactly what they are adding to a collection.
