Have these two 1957 D Pennies with BIE ERRORS. Also apprear to be rpm, how bout the doyblido? Didn't see a variety with the bie myself but thought I'd check here. Apologise for two coins in one post, u can make two separate if anyone is having trouble ,i know it can be confusing with the pictures
Not nearly identical but nice finds. BIE's can take on many forms. There are so many of them that you probably won't find identical ones. No to DDO
Same die? Tough to tell, but I don't think so. The 1st coin has some chipping just below the lower loop of the B. The second coin with a bigger chip in the middle doesn't have the same chip under the B. That's why I don't think it's a progression.
