You might give APMEX on Dean McGee Avenue a call. They used to deal in numismatics and gave me a much better price than any dealer I could find in Tulsa. Good luck.
Sal at S&N Enterprises on Highway 37 just west of I-44. I do all my silver and gold trading through him. I've been to every dealer in the metro and he's my go-to-guy. http://sandncoins.com/
I can highly recommend Flying Eagle Coins at 9118 South Walker, OKC, 73139. The do make a modest profit but certainly do NOT rip you off. Good people doing good business. They have a website that will give you an idea on pricing. flyingeaglecoin.com They are working on keeping the website up to date as far as inventory so call ahead if you see something you like. Pricewise, I got a little better pricing in store. If you visit them and don't see what you want just ask. They most likely will have it in the back. Last visit I bought 12 mercury dimes and a 1971 40% silver ike and got out the door for less than 35 bucks. Try beating those prices on the net with shipping and all. Great place. Check em out.
