I have two unrelated collecting hobbies: Transformers of course, and second, coins.  These two collecting worlds really never overlap, so you can imagine my surprise when someone told me about 2 Transformers branded and licensed legal tender commemorative 99.9% silver proofs.

Little island country, Tuvalu, is too small to mint their own money.  (They are actually too small for lots of things - wikipedia cites their largest source of income as "foreign aid".)

Minted in Australia, but Tuvalu $1 commemorative proofs, one coin features an image of ROTF Optimus Prime with an Autobot symbol, and the second features ROTF Megatron with a Decepticon symbol, and the Transformers logo.  Both are 99.9% pure silver, feature the Queen of England on the other side, and come in a collector case.

Any other coin collectors out there?  To my knowledge, this is the first time these hobbies have ever intersected.  (also the first Transformers product produced by a national government.)
