20 Dollars Doni Tondo

Palau has built one of the more aggressive bullion-and-collector programs in the Pacific, routinely licensing major art works for large-format silver issues aimed squarely at the European collector market. The Doni Tondo — Michelangelo's only surviving panel painting, housed in the Uffizi since the Medici acquired it in the sixteenth century — has appeared on coins before, but the 65mm format allows reproduction at a scale where the painting's complex tondo geometry actually translates with some fidelity in relief.

The frame of the original is considered as significant as the work itself, carved likely by Francesco del Tasso around 1506.
