FarmVille Pot of Gold redeemable prize list *Spoiler* [Updated]

So far, dedicated farmers have discovered the following items: Shamrock Sheep (10 gold), Spring Flower Cart (20 Gold) and the Leprechaun Gnome (30 gold). Check out FarmVille-ian Cordelia's image (above) of what these items look like on the farm, and how the pot of gold transforms once it starts to get full. Nice to see such a bright splash of color on the farm, especially after the long winter!

Here's what the items look like when you open the pot of gold (courtesy of Light Chan).
UPDATE: All redeemable prizes have been released and the three last items include the following: A Spring Pond: 50 Gold, a Lucky Fountain: 75 Gold and a Shamrock Castle: 100 Gold.
