FarmVille mystery chest: What did you find inside?

A select group of farmers have run across a special locked box, aka the FarmVille Mystery Chest, while harvesting fields. To unlock it, you have to (if you haven't already) give Zynga your email address, and the game will email a code to open the box. Once you receive the code, head back into the game, enter it and - voila - the FarmVille mystery chest will burst open with a surprise inside.

Players have been finding all manner of items in the boxes, including a less-than-exciting golden chicken to the slightly more exciting Mammoth Statue.

After the break is a list of prizes found in the chest so far:
