Don't know why its takin me so long to find this forum but glad I did. I know this is a long shot but several years ago my truck was broken into in Baltimore Md. and the one thing that hurt the most was they stole my X metal pennys. its been so many years that I hope they found there way to a good home, I have since gotten a replacement pair. I bring this up because going through some boxes I found my old box with the serial number on it and my old receipt. the number on the box is A16414. they were polished with black lens, I believe PB016414. im not looking to get them back just hoping they made it to a good home, maybe match the box and coin back with the glasses. thanks for taking the time to read this and have a good one.
