I am new to posting on here so I apologize in advance. I found a quarter just the other day but it was a 1979
no mint mark. I am not saying it's not wear, but I have been looking at coins for a while now and haven't t seen one like it. Mine is noticeably different and has a sparkle to it. The lettering looks different and half of the letters are worn off. So it definitely could be just wear but I thought it's worth bringing up. I can send a pic if anyone is still interested
