Didn't see this mentioned, so I thought it might be helpful. If you are going to buy pre-1965 coins go to coinflation.com to check the current melt value. Story below if you are interested:
I checked coinflation before a recent purchase of a few half dollars my daughter wanted and the melt value was a hair over $12. I went to a coin shop I had visited a few times in the past and had very good luck doing business with, but the last time I was in there another customer was looking to buy some generic silver rounds and they wanted to charge him extra to pick from the tub they had instead of the store randomly grabbing the rounds (it was a decent dollar amount, not just one or two). They had let me pick through the tub in the past no problem (I picked out a couple in sealed packages, some hunting/fishing ones, and a few Christmas styles for future gifts). Something told me they bought a lot at the last high spot near $40 and now were being forced to sell them in the $27-$29 spot range and were looking to pick up extra money any way they could.
My daughter had given me $40 and I told her I could probably get her 3 Franklin halves as she's a big Ben Franklin fan/admirer. I asked the shop for the three halves and he checked his computer and said they'll be $17.95 each. I told him no, I didn't care about dates or graded condition. He went and talked to the owner or guy in charge and came back and said yeah, they'll be $17.95 a piece. I said "really? Thanks, but I'm not interested".
I immediately drove to another coin shop a little further away that I'd also been to before with positive experiences and told them what I wanted. The guy pulled out a small bucket, placed it on the counter and said "there you go". I picked out 3 nice ones, he pulled out a pad to write the receipt and said that'll be $39.25. I paid a little over a buck melt value which included at least 6.5% sales tax (depending on any additional local taxes). More importantly I saved about $5 each (with tax the other shop would have been over $18.50). Needless to say they are my new local coin shop.
Regardless of where you buy, know the current metal value of the item you are buying. Good luck, I don't see how you will regret it long term.
