I am a hobbyist. I know my way around the coin world, but readily admit I am not an educated numismatist. So this may very well qualify as a dumb question. My apologies if it does. Ever since I been financially able, I could never pass up an old $2.50 or $5.00 Indian with the incused design. They just intrigue me and I own... Well, I own a tribe anyways. None are graded and that suits me just fine. Just was looking a a video by @asheland showing a high end Indian. The fields almost appear polished to me. Hence my question. When these cross a graders desk, what are the criteria? Is an incused Indians grade based on the wear of the fields? In effect based on how nicked and banged up the field is?
