I've recently started looking for errors. noticed some cracks in Lincoln head and filled dates and mint marks. are these "errors"? is there any market for them?
IMO, they are fun to collect, interesting to study, cost virtually nothing and are sought after by many roll hunters. Some call this part of our hobby "micro-numismatics. Will it make you rich? Absolutely not. Try and sell one just to see. However, it will possibly add years of enjoyment to your life. In the 1960's there was a paperback book published by a man named Spadone (sp?) mostly filled with oddities and micro varieties like this.
Technically, yes....as they're unintended, but generally speaking, they're so common and insignificant it renders them meaningless. As for any "market" for them, unless one wishes to fluff them into being something they're not, no... not really.
You're very welcome. It was a perfectly reasonable question, and asking is how we learn. Welcome to the forum.
Common error/variety with not much premium This is from the NGC website - quote "NGC does not attribute as varieties coins that display Strike Doubling, Abrasion Doubling, Die Deterioration Doubling, Master Die Doubling (doubling that is found on all coins made produced from that master die), insignificant die chips, breaks, cracks or any variety coin that falls under mint tolerances for doubling or normal die wear." closed quote I want to share this webpage with you - https://www.ngccoin.com/variety/
