One of the great mysteries of the universe: why didn't the Sacajawea dollar coin take off? I've always found them eminently useful and preferable to digging around in my wallet for small purchases.

Via Quare, I learn that the Federal Reserve may be planning to produce new $2 bills for the first time since 1996. For some odd reason, Ann Arbor (Mich.) seems to be awash in the bills. Like the dollar coin, they’re one of the useful things that seem to have dropped through the cracks.

One of Signifying Nothing’s first posts was advocacy for the $1 coin. Now, I see (via Justene and Dean) that Boviosity! is leading a challenge among bloggers to get more dollar coins into circulation. Sounds like a plan to me.

Update: Matt of it could be a lot better… is feeling contrarian on this one.
