Post Your Wyoming Saddle Horn DDR State Quarters!

Yeah, go for it MOS0239! I am all for making this a "post your Wyoming DDRs" thread :)

Sounds good, look forward to seeing them! Yes, in my experience the vast majority of all single squeeze DDR/DDOs are on Philadelphia minted coins. The explanation I have heard is that the Denver mint has newer machinery than the Philly mint, and that as the machinery ages, it gets a little loose, which is what allows these single squeeze DDR/DDOs to happen (basically the hub begins slightly out of alignment with the die and snaps back into place as it begins to squeeze).

Wow, excellent find on the D! That is much more significant than the ones listed on Wexler's site.

Nope, doesn't appear to be listed, but definitely a DDR (and a pretty good one). I was curious since I have not dived as deep into this as I should have before. My explanation was slightly off. These center-design doubled dies are actually caused when the hub initiates contact with the die slightly out of alignment and a mint employee stops the press and re-aligns the die. Because the un-hubbed die is convex, the highest point of the center of the hub will be the first thing to make contact with the die, and that is what gets doubled. The thing I described about the die snapping back into alignment is actually what happens on peripheral device doubling on single squeeze dies (i.e. when the mint employee *doesn't* see that the hub is out of alignment and the die is pressed until the pressure snaps it back into proper alignment with the hub distorting not only the center, but the entire design). Here is a good write up on error-ref http://www.error-ref.com/doubled-di...n%20started.

Excellent explanation. I've gotta digest all that a few minutes.

I gotta wrap this up and hit the rack. Talk to you tomorrow.

Wow, those are some very nice ones! Congrats MOS0239!
