Wow! I remember you from when I joined in the mid-Noughties under a username I've since forgotten. The site software was more primitive back then IIRC. However it's been much the same for the past 10 years or so (I'm both Peckris and Peckris 2).
Colin Cooke grade their best items quite accurately I'd say, but Fine has been their Achilles Heel - a general grade they use for all coins Fine or less, as long as the legend is complete. I'd agree with the consensus that your farthing was overgraded, but hopefully your visit here will reignite your passion for collecting.
