Certainly the single rarest US quarter is an 1866 proof version - only one of these was struck, and it's impossible to put a value on it.
The quarter with the highest market value is a 1795 Draped Bust variety with a small eagle on the back. As of 02/2011 a top-quality one is priced around $450,000.
Several other quarters fall in the $250,000-$550,000 range, including 1805 and 1873-CC.

You think the rarest would be when they made some of the first US quarters in our history.
A 1765 US quarter does not exist.
Oklahoma had the lowest number of mintages at about 416 million, so there are much less of those in circulation.

Rarest mineral in the US
It depends on what part of the US. But the most rarest silly bandz are: Ocean/Waves, Justin Bieber Pack, Cyclopse, Glow In The Dark Microphone and the last one is Glow In The Dark Unicorn On A Rainbow. These are the most rarest silly bandz in the US.
There is no real data to tell us what the rarest marine fish is. Likely the rarest fish has not yet been discovered, because it is so rare.
Indian head penny
I assume you want to know what the rarest quarter is, either in terms of mintage or value. By mintage, it's a tie for the 1873-CC and 1827 issues with only 4,000 of each struck. For value, it would almost certainly be a quarter dated 1804 (not to be confused with the legendary 1804 $1 coin) that sells for nearly a half-million in top condition.
