Our Story

Family-Owned & Operated

Massachusetts Coins Dealer

Curiosity Coins has been put together by William Halchuk. A coin collector myself since I was a young boy. It’s a coin business build by a collector/dealer for collectors to have a new type of experience. A no pressure atmosphere where we sit one on one to go over what you are selling or buying. If you are not a collector and know nothing about coins, I will go over everything you have and explain what it is and what values it holds.

Curiositycoins.com is a family-owned and operated business. We are located just outside Boston, Massachusetts. We strives to deliver you a perfect experience in purchasing collectible coins. We are a member of NGC and PCGS. We have been a merchant with Amazon since 2014 and Ebay since 1999.
