I've never been to one but have kinda wanted to go check it out just to see what it is all about. Just the variety of coins would be awesome to see.
FB - I can see the over pricing you mentioned taking place at these shows.
I made some very nice deals, believe or not, at a flea market. I have just started buying some coins and I wanted to get more half dollars. Other than the Walkers and Franklin's I have found the only really old halves I have is a Seated Liberty I bought a while back and the one Barber I found in a box not long ago. At this flea market there is an elderly gentleman...64 yrs old...who was a CRH'er when he was 15. He dad drove a bus and he would go through the change box after his dad's shift pulling different coins out. He also mentioned he would CRH the large dollars and pulled many, many Morgans. It was fun listening to this old guy.
Anyway, I bought three Barbers halves from him this past weekend. One was a 1915 for $8 or $12....one of the three was a little more than the other two so maybe it was the 1915. When I got home and checked the Redbook I was shocked to see the low mintage on this 1915....only 138,000. No expert here but I would say it is G-4 condition...no better. But for the price.....I thought that was a great deal. The Redbook lists it at $85 in that condition. I also hear the Redbook is a little over priced too but I don't know. I am still learning this coin business. I bought 4 Morgan dollars (two AU), 3 Barber halves and 10 Indian Head cents for $100. I thought that was pretty good. He also has a roll of BU Wheat's that he bought as a kid while CRH'ing that he wants $8 for it. I haven't looked that up to see what it is worth yet, but I will probably buy it if it is even close to that. Since he was CRH'er so long ago, he probably got all of his coins at face.
I have rambled enough but I will finish with this....this guy said he is trying to sell his collection because if something would happen to him, his wife and kids are not interested in coins in the least. He thinks his wife would just cash them in at the bank. I will visit him a few more times soon.
