I think I found my first partial collar. I checked error-ref.com and can't find a link with pics. It is a 1983-P Jefferson Nickel. It is not evenly spaced all the way around the edge so could it be a tilted partial collar? Check out the pics and let me know guys. I have full obv & rev pics. The next is the thicker, then the thiner, then one in the middle on each side of the thicker and thiner. Thanks!
Looks like a good candidate for a partial collar strike based on the photos of the edge (not the rim).
Sorry. I was referring to the file names of some of your photos of the edge: rim-thick.jpg, rim-thin.jpg. By the way, congrats! That's a very nice find.
