I do think that all but one of the coin shops in the Denver area are 'good', and have fair retail prices for the most part. You can tell who follows Greysheet 'Ask'...
It does seem that every shop has at least one overpriced item

, but when you can see a coin before you buy it, it's easy to pick the best 'eye-appeal' coin for the grade.

If you can get what you know is a great-looking coin immediately, versus having to judge from pictures on
ebay and waiting for shipment, then "Greysheet Ask" is quite fair I think. Frankly, I won't do
ebay unless it's below Greysheet Bid, or I can't get the coin locally... And Modern Uncirculated Mint coins in O.G.P. are usually a better bet to buy sight-unseen than classic coins like Morgans....
