Hi Have a question. While going thru some pennys i noticed this 1973 penny has what appears to be a very high ridge line on the side where liberty starts and continues up towards the word in. It also appears to have a crack like it is seperating. Just curious as what causes this. Is it from the die from the mint or normal wear and tear. I have noticed it on numerous 70's pennys and was wondering if it is a common for that year pennys. Sorry if this is the wrong section to post this but wasn't sure where to post. Thanks for any info
