Al;
Have tons of older dice that I have collected over the years. I need to dig through my boxes of dice to find them. I just took a quick glance and my boxes I have not looked at my dice in a while, boy - some dice can age and deteriorate really quickly - Have some imploding dice and some are crystalizing. Looks like the hot stamps can go quickly also. I think I better put them in airtight bags so I don't have a chemical reaction and lose my collection.
I know I have a dice from the Humbolt in there somewhere. I will e-mail you with my results of my "dig".
