Hey I was wondering if anyone here ran a coin shop. If you do could you please message me, I am trying to figure out some pricing and back end questions.
Not for nothing but your best bet is probably to do a Google search for shops in your area. They would be willing to answer questions on the chance you might be a paying customer.
Or simply post your questions here so any owners can reply without investing lots of time.
Grey sheets are used as a reference but the trend has been using sold auctions from ebay, Heritage, and Stacks. These sites offer real time pricing and what a coin has actually sold for and even the Grey Sheet can be too high for certain coins. The market is changing.
I am a full time dealer with a brick and mortar and go to at least two shows a month.
