For coins, especially error coins, because the proof is in the pictures of coins, especially when a buyer is 2000 miles away and he wants a clear picture of something the naked eye cannot see. Absolutely an outstanding microscope all the way around, I had it going in 15 minutes by myself, and it takes nice pictures and got to love the 1000X magnification. By far the best overall digital microscope I have ever owned.
