Auctions and raffles are commonly used to fund public goods. We run fundraising events in the field at the meetings of a well‐known service organization across the United States to examine the fundraising properties of five mechanisms: one that is common in the literature, two that are familiar to practitioners in the field, and two that are new. Consistent with a novel model assuming independent private attachments to the charity, we find large differences in the performance between the two most familiar formats, but these disparities are dwarfed by the differentials achieved using the new and less common formats.
