I want to open a stamp and coin shop. I don't know what kind of name to take.

Three or six words are good, such as Tongbaoge, Bao Tong Post, Coin Club, and all by election, which means money and parity. The porch is elegant, and the name of the coin stamp should be elegant, like Audi A6, low-key and luxurious. I hope it helps you, and I wish you a happy working life.
