Where do i find really cheap U.S. coins?

First, I got yelled at when I was a 12 year old kid for asking for cheap coins. I walked in to a coin dealership with something like $4, and I wanted a cheap coin and asked for one. The dealer scoffed, “We don’t sell cheap coins, but we do sell inexpensive ones”. I learned the lesson. Anyway, go to a coin dealer and ask to see “well circulated” buffalo nickels or eisenhowers. They’ll show you some pretty inexpensive ones.
