About us

History of TCG

Twin City Gold was born out of a passion that began in 1964, originally founded by Raymond Nadeau as the Biddeford Saco Coin Shop. The business opened in 1970 and has been in continuous operation of buying and selling coins, jewelry, diamonds, pocket watches and more ever since. In 1990 the shop’s name was changed to Twin City Gold when ownership was transferred to employee Tom Sangillo. Tom expanded the business and brought Twin City Gold to its premier position as the largest dealer of used and estate jewelry in New England.
