I snagged this little die (or "this little dice" if you're a Brit) at U-Con last week. I shall call it "Mini-d20." Here it is next to it's normal-sized low-impact (read: sucky, yet nostalgic) d20:
The Mini-d20 is numbered 0-9 twice...a configuration that some old-schoolers prefer. I like having some in my pile, but I would just as soon grab a 1-20 numbered d20 when I need one. It's all personal vibe, though.
I'm not sure what game these mini versions are from. I don't think I've ever seen them before. Maybe some googling is in order...hmmnnnn.
Anyway, I filtered thru a fishbowl of dice at one vendor's booth, and a box-o-dice at another booth, and ended up with several to add to my collection. Here's the gang:
Several of those mini-d20s, an old (I'm presuming) Basic or Expert D&D Box Set light blue d6 (probably Moldvay or Mentzer set), that normal-sized sucky d20 referenced above in the 1st pic, and three Gamescience d4s of various colors Again I'm presuming these d4s are Gamescience, cuz I have a full purple set and these are identical to the d4 that Colonel Lou Zocchi made in that set (those dice rock, BTW):
Ah well, kinda boring I guess, but I like finding these treats in a mound of modern/regular dice. These folks probably think I'm nuts for wanting the crappy ones, but I dig 'em, and that counts too!
