Yeah, the 1/2 farthings offer a slightly larger canvas and details to enjoy, but the 1/4 and 1/3 farthings are my favorites just because they are so diminuitive. I have an 1854 1/2 farthing in NGC MS66 BN with lovely purple-blue toning. That will be going to Mark for imaging later this year. While not as vibrantly colored as this 1/4 farthing, the surfaces are wonderful. That 1770 1/2d is wonderful to ogle. It used to be the highest of 3 graded PL for the entire series until last year when someone made a 65 RD PL. I like mine better though, as the 65 had some spotting, not to mention it cost 10x what mine did... and I paid strong money for mine (it languished unsold in dealer inventory for quite some time, and then they put it on eBay and I was the only bidder... maybe I overpaid, who knows, but I love the coin). The coin below is interesting. It was sold in an NGC PF64 BN holder, but the dealer said he believed it was incorrectly holdered, and is actually a prooflike MS strike. I sent it back to NGC, and they concurred... it is now certified as MS64 BN PL. Considering that prooflike examples from this era are infinitely more scarce than proofs (in my experience at any rate), it was a very nice pickup for $250.
