Excuse any errors in this post I'm using speak to text to post this I was cleaning out my passed away uncle's camper and come across this Penny it is a 1995
no mint mark dull gray penny the sides and sickness or inconsistent the sound sounds different when you drop the penny compared to another penny it feels different I've tried looking it up I can't find nothing I did read that they can change the color of a penny by doing certain things I'm not a collector so I don't have all the fancy coin collector tools just my phone I've tried taken as many pictures as possible that would explain anything I'm trying to say any information would be awesome I'm just super curious I keep trying to upload the images and because maybe I'm on the phone I can't do it I'm not sure please help
