here and see the Koplow dice set, or its modern equivalent, that I purchased back in 1987 at King's Hobby Shop in Austin, Texas. It was the 10-piece tube (though I remember it being 9, one less d6) that included 1d4, 4d6, 1d8, 1d10, 1 tens 10, 1d12 and 1d20. They were transparent red dice with white ink. And they were my first color-matched set, used to run my very first Robotech games as they were purchased the same day I got Robotech Book 1: Macross from the same shopping trip. I use my modern clones of these original dice in the 5e D&D game I play once or twice a month, but let me tell ya- they don't roll like those first ones did. Natural 1s all the dang time.
Honorable mention goes to the 20-sided d10s I got in my FASA Star Trek boxed set purchased for me by Mammaw and Pappaw Webb when I was in the 7th Grade, and the almost completely rounded d20 I used to play Lone Wolf game novels in algebra class my Freshman year. I still have all three of these dice, and they are in the same keepsake bag as my first set.
