I was recently fortunate enough to find a little hoard of these at a London Coin fair. All the coins are UNC and as struck, but I've split them into 2 catagories. These here are the lesser of the stash (but only just!). They have good lustre, some are toned unevenly and some have slightly spotty of streaky toning. There is minimal evidence of mass production.

These are lovely examples of the last ever fractional farthing and are priced over £10 less than the other 1913 third farthings in the specials area. The picture used above is one of the others, but I guarantee you won't be dissapointed!
