All 3 items purchased were high grade, which is great for my collection. Prices competitive, combined shipping, shipped quickly, got exactly what was depicted by Seller in each instance & arrived safely in 2x2 for inclusion in collection. An absolutely fine transaction & would be glad to deal with Seller again on lot(s) of interest. 5 star performance.

Packaged well. Coin was a described. Shipping charges was fair, unlike most sellers who try to make a profit on what they charge you to ship you. I recommend doing business with this coin seller.
