Glad you asked about the dates. I hadn't looked closely and I see they are not all the same:

500 lavender 5-1-96
1000 yellow H&C 12-31-96
1000 yellow house 3-1-96
3000 green house 3-1-96
3000 green H&C 12-31-96
5000 red house 3-1-96
5000 red H&C 12-31-96
10000 blaze orange H&C 12-31-96
2000 black December 31, 1999

There may be another 10000 variety that I do not have.

I traded for these. They are expensive to buy. Ask one of the original Trop museum partners who found them what they are worth.
