William IV farthings in the absolute top grades are really well sort after , most fetch over £100 there does seem to be a lot of them around but most are in good fine or less , with a few nicer ones in GVF and lower.
The smallest bit of wear on Williams bonce loses the coin a lot of value.
High grade examples tend to just stay for ever in good collections or be sold by the london auction houses .
Ebay is pretty useless for high grade William farthings as well , you have to wade through piles and piles of rubbish to find anything decent
