If modern working hubs are fitted with slots that form keyways so that the working dies must fit in the slots, then how do doubled dies as dramatic as the 1995 LMC DDO occur? Are the keyways evenly spaced so that if the hub is rotated far enough then they will fit? And if that is the case, why wouldn't the rest of the design be involved? Whether that is the case or not, how are the 2009 "skeleton" finger DDR's formed? Are those just glorified trail dies from the elasticity of the steel trying to "snap back" after the pressure of the hub is relieved?
The answers to your questions will still be being debated long after you and I both are long dead and gone.
For one thing, the 1995 was not produced using the single-squeeze hub. That did not come into use until 1997. As for the 2009...what GDJMSP said.
Thanks guys, I thought the single squeeze was put into effect a little earlier. So, with the exception of minor spreads that can occur from annealing the dies, are nice doubled dies (like the '95) a thing of the past? Have they been completely eliminated? That would be kind of a bummer to not have something to look forward to.
That remains to be seen. According the the mint, single-squeeze was supposed to eliminate ALL doubled dies, but that hasn't happened.
My feelings exactly. I guess anything is possible, but I just don't see any way for any of the classic Class 1 doubled dies to be produced given the modern methods.
That's true. I think varieties such as the 2009-D DC quarter are going to be about as dramatic as it gets with these newer class viii and class ix doubled dies. Given the nature of the doubling and of the conical shape of the dies, these will almost certainly be limited to the center areas of the coins. When searching, I hardly pay any attention to the outer devices on coins produced from the single-squeeze process.
I hadn't really picked up on that before, but now that you mention it, the '09 fingers, the '97 double ear, the '06 ear nub...
