A very minor, and common, filled die error. Grease or machinery oil was on the die when this coin was struck, preventing the design elements from being fully struck up on the coin.
Thank thank you sir any worth? I really need help how to post a thread takes me forever still new to site
Yes, it is doubling- machine doubling apparently. Here is an example on a 1 cent coin: http://www.error-ref.com/machine-doubling-on-both-faces-of-the-same-coin/ https://www.ngccoin.com/news/article/5688/Double-Dies-vs-Machine-Doubling/
Grease filled Die on the first coin and MD on the second coin. No extra value but neat to add to your collection. Welcome to CT.
