I have two (well quite a few) different wheat cents. But, as I stated above, both contain the dates punched over top of mint marks. And, they appear to be from the Denver mint. Have these been discovered? I couldn't determine in my searches. Sorry, having trouble uploading images...tried several times. Unfortunately, I only have my phone as my connection to the interwebs. Thank you, in advance, for all help and advice. Also, have a few 55 and 58 errors, but, not as prominent, as the ones used as references.
