I probably have in the 2000-3000 range, and I have been gaming for 21 years. I have tons of dice nobody has every heard of, including ones that look like puke, d5's, d7's, d16's, d30's, d50's, d100's, and even a set for d10,000! Also alignment dice, critical hit dice, hit location dice, fumble dice, noise dice, wandering monster dice, a round d6 with a ball bearing in it, etc.
