I recently lost my grandpa, and while we were going through his things we stumbled across his coin collection... It was only a hobby for him, nothing he took to seriously but he amassed a collection that actually had a few neat coins. I knew nothing about coins prior to acquiring my grandpa's coins so all the information that I have has come through google searches and coin forums. I would appreciate ANY information about the business of coin collecting/buying/trading. Especially what I should be looking for and the values of the coins. Thanks for your time!
