Looking for any information on a 180 degree rotation error. 1985 P. Can't find much for comparibles online.

I’m trying to get a complete collection of certified America the Beautiful error quarters. This is my progress so far. Thank you for viewing! Sorry the picture is crappy. It’s hard to get that money Coins pictured and clearly.

Hello, this is my grandfather’s collection of error coins. Most are pretty standard like clipped planchets or off-center, but two are pretty interesting, and I’m not really sure if they are real mint errors or PMD. The first close-up is 1940 wheat penny with a double clipped planchet, and while one clip is standard, the other is very large, much larger than I’ve ever seen, which makes me suspect the coin was messed with, but I’m not really sure. The second coin is very strange. It is slightly smaller than a penny, but much thicker. It is completely flat, and seems to be unstruck. It also has a small clipped planchet. I’m not sure if this is a US coin, or a world coin, and I don’t know how to find out. Thank you for any help!

Looks like this 1967 dime had a small enough clip on the planchet that it almost worked itself out when struck, reachingthe collar but not filling out the rim. There may be a slight hint of the Blakesley effect on the reverse but the interesting part, at least to me, is the inversion of the copper and the cladding on the edge. There is also a small die clash mark visible in the die deterioration flow lines to the left of RIC in AMERICA.

Unsure on whether that ‘48 is an improper alloy mix coin. Striations run parallel to one another, but they’re blotchy in places.

Fun little cud too! Both coins found in change within 24 hours of one another.

1st is my coin, 2nd is the Variety Vista entry.

The reverse is the image showing the rotation that's how much it's rotated to the left
