1. Coin Catalogue - Gift him a coin catalogue for rare and unique coins. It can help him keep track of his collection and identify the value of the coins.
2. Coin collecting book - A book related to coin collecting, such as The Official Red Book or The Standard Catalog of World Coins. These are great resources for beginners as well as experts.
3. Custom coin holder - You can also gift him a custom coin holder that he can use to display his favorite coins. It can be made of wood or glass, with his name or initials engraved on it.
4. A rare coin - Why not add a rare coin to his collection? Do some research to find a rare coin that he doesn't have and gift it to him. He will be thrilled with this addition to his collection.
5. Coin cleaning kit - He might need a coin cleaning kit to keep his coins in good condition, so this is something that could be useful to him.
