Hello. So I've recently begun searching through rolls in my spare time and I came across this peculiarity. At my first glance I almost tossed it aside, thinking the large splotch to be some sort of dirt. I examined it further, and realized that the splotch was a mirror-image of a portion of another penny, complete with indented E pluribus unum and united states. The splotch is the same material of the penny, and not anything that can be scraped off. Here are some pictures: So what is this error called? Is it common? Is it even an error?
I'm not an expert at these but it looks like post mint damage to me. Like that lump was struck with another coin and a hammer then attached to that coin. But you'll get others to reply soon enough that know what they are looking at better then me.
That is strange looking. I've seen many times when some adhesive was used to join two coins together. That's what I expect you may find. Acetone will tell.
It's not an error, it is raised off the surface and is residue of some kind of adhesive that was used to glue two coins together for some unknown reason. Thanks, Bill
Even if the lump is copper,it is easy enough to melt some with a torch and press between two pennys,it'll stick to one. Interesting no the less,but it could be duplicated easily which is something that I look at when looking at errors,it won't be worth any $$$$value if I can make a dozen in the workshop!
