This auction I won for a very nice condition Basic and Expert D&D set (along with the Caves of Chaos and Isle of dread) came in the other day and I'm still shocked I nailed it for $30 with free shipping. The retailer on Ebay was not a regular RPG seller, and the pics were honestly misleading as the books are in better shape than they look from the photos. But what was most shocking...both original dice sets (or damned close) came with the Basic and Experts. We're talking unused original "gumby dice," the kinds that required a grease pencil to see the numbers and with enough rolling would turn into smooth spheres over time....but completely unused. Wow.
My players and I coined the term for these old dice as "gumby dice" back in the mid to late eighties to identify those dice which had been worn so smooth you couldn't even see the numbers anymore. I have one decades-long gaming cohort who still uses his original set from the late seventies, although mostly for the terrifying novelty of watching him roll a D20 labeled 0-9 twice (with a D6 to settle the "1s" or "10s"). The dice with this book set appear not to be the "original Originals" in that sense as the D20's are number 1-20, but they're still damned close.
