Thank you for being interested about this matter, Jay Johanson. It is very kind of you to take into consideration such possibility. Indeed, some projects organized raffles in past months and all users interested in collectibles appreciated the prizes. some were very nice items (cards, hardware wallets). At same time, as you see in other replies, some forum members would prefer prizes in BTC, for preserving their privacy.

My opinion on this is, besides the fact that it would be a very nice gesture, that you can try make some raffles with prizes in physical items but also raffles involving only BTC prizes. Maybe make a raffle with a physical prize, then one with BTC prize and so on. Of course, the budget matters a lot, and only you can know what budget you have at disposal.

Regarding raffles with physical prizes I have an idea in mind, but I am unsure if it can be done... I am thinking about some coins made by casascius or Kialara. Or, why not, coins made by smoothie, so some Lealana coins... Such coins are very rare and I did not see them used as prizes in any raffle (raffles organized by other projects, that is). So maybe such prizes would be very unique.

Again, the budget is crucial, but I hope my ideas will help.
