Hey guys! I recently was able to start my own collection after being inspired by my grandfather's amazing collection and I'm still learning all the different kinds of errors. I wanna get more into selling, trading and accumulating all kinds of errors and what not. This first quarter is .2 grams lighter than average and feels a tiny bit rough compared to a normal quarter and it's much darker. The "T" in trust is completely smoothed over. This next quarter looks like all the text around the circle are being smudged up towards the rim on both sides. This penny has some kind of extra circle outside the rim on both sides. This penny along with a few others I have found, have some kind of oily or greasy textre on the entire coin on both sides. (Teied cleaning, it's definitely embeded in the material.) This coin also has an odd texture of a series of lines across both sides. I have a few of these from different years, tried cleaning one and it's also definitely apart of the material or manufacturing error, whatever you guys call it. I would like anyone's opinion on this dime, I feel it's a true cud because the rim follows the warp, but I would love second opinions. I have more I would like to share, but I reached my limit for this post. Any helpful tips, advice, input or opinions would be really appreciated!
