This is another find off eBay. It's described in the Snow guide as S-15: "1 and 88 in denticles", but I think I see an RPD at the base of the 1 as well. This particular example is a nice, honest circulated example. The latest Snow guide describes this variety as "only one example seen", so this is #2, 3, or 4... The "1" digit in the denticles is sorta vague, but the "88" is pretty clear to me. I'm honestly unsure if there are 1 or 2 arcs in the last MPD, 2 would suggest an "8" punched twice.
