We have done it two different ways. One is what is called(I don't know why) a Chinese Auction. People bring what they want to put in sale lay it on a table in groups. You tape a brown paper bag under each group. Then you sell tickets (like 5 for a dollar). Each person writes their name on each ticket. Then they can go around the tables dropping as many tickets in the brown bags as they want. Maybe in only one or two, or they might drop a ticket in each bag. When all have finished doing this. You take each bag, shake it up so tickets are mixed and draw a name. That person is the winner of that group of treasures.
