The Golden Palm (3.5e Equipment)
From D&D Wiki
The Goldem Palm: This mace is a brass shaft with brown leather wrappings around the handle, with a heavy dull orange brass fist clenched tightly. The original was said to be crafted from Garl Glittergold himself, and since then duplicates have been made all over. This heavy mace is a favorite with clerics who busy themselves with merchant work.
It is a +1 heavy mace. 1/day, the command word Gilden can be spoken as a standard action. This causes the fist to open, revealing a single gold coin. Once removed from the fist the hand automatically closes.
