Hi All Im very new to coin collecting but just inherited a small random "collection" - I explain the story more in the introductions category - Anyhow been sorting it and having fun with the foreign stuff. A coin collector friend of mine came by and took a look and saw this coin and said "oh this is cool, a CUD error!" I had just separated it because at the time i was determining what coins were silver, and it looked like a nice coin condition wise for being from 1891 - Threw it in a 2X2 and there it sat. Now Im going through these again and I wanted to know your thoughts - The CUD is on the back at 7 oclock Also- as a rookie here - wondering what the condition of this might be as I see they can be worth over $100 in XF40.. But the grading is still hard to wrap my head around. Also - does the CUD make it more valuable? Sorry if these are super basic questions, Just trying to wrap my head around this while dipping my toes into a new hobby! Thanks!
