I'm shocked -- shocked I say -- that David Akers called this an "unecessary" denomination. How else were people expected to purchase a hundred Three Cent stamps in 1854? Yes, it was an unusual denomination, but collectors today are certainly glad they were made.
Akers was correct that this is the second most comon date of the series. The 1878 $3 is the big winner and the 1874 is a distant third, with all other dates way back in the pack. Hundreds of Mint State 1854 $3's exist, mostly in MS62 followed by MS63, then MS64. Gems make up only a small percentage of the Mint State population and anything above MS65 is extremely rare. The best example is a PCGS MS68 that sold in a 2004 Heritage sale for $112,125.
