There is much talk about how the Internet has changed how people shop. That includes shopping for coins. You could just sit at your computer and find that coin you've been looking for. You can browse sites all day. But there's nothing like attending a real show, in person.
--for the interaction with real people in real time
--for the close up look at many exhibits, all in one section of the floor
--for the walking around and looking and spotting friends
--for the special displays of special coins
--for the chance you may find that special coin
--for checking out coins in person, with your magnifier
--for being in one busy place with people who share your love of numismatics!
I will keep attending as many shows as I can, in person, for all of the above reasons.
