Now for some of the extras: a Gen 4 prooflike and a Gen 5 deep mirror prooflike. My photos don't show off the mirrors at all but they are there. You could argue that the 1904-O PL is closer to a semi-pl and that it would not meet the stricter standards of today. The DMPL is closer to making the designation but again can be argued that it is more of a PL+ than a DMPL. eBay seller image: GC Image:
Two more of the extras are featured next: a Gen 4 MS 62 UDM and a Gen 5 AU58 deep mirror prooflike. The UDM, like most of these, has very strong mirrors. I have held a few over the years and they always impress. The AU 58 DMPL has strong mirrors as well and a bit of wear explains the grade.

And that's the set so far; there is an MS 66 example but it is an "S" (San Francisco mint) so it's not within the parameters but I'll probably post it at some point if an "O" does not show up beforehand.
My second effort at an AU 53 proved successful (lost my prior try)! I added this Gen 6 for a reasonable $51 (reasonable in terms of what I'm willing to spend for the set; most would still consider that high for a low AU common date). The coin looks decent (seller's photo, which is below, made it look a bit worse).
