I think it is a silent auction. So you go in and put your bid. So it is not going to be like what I believe you imagine.

I am not sure whether 1. you know what others have bid(my guess is this would be the case to raise more money from charity's point of view) 2. you can bid again.

The way silent auctions (charity or otherwise) I've participated in usually do it is to have a list of bids near each item. You can circulate throughout the evening, changing your bid until bidding closes.
