Another worn out Farthing... NEWP - Update

Here's my latest meager find. Well worn, but these are hard to find in what, to me, is affordable condition. Heck, they're hard to find in ANY condition, but at least now I can say I have one. 
These are the sellers pics. I'll update with pics of my own, when it arrives (should be any day now!) I'm not sure my pics will be much different. A nearly slick copper disk with the faint reminder of what used to be there.

well the more worn the coin the more stories it will have to tell, whose pocket or pouch, were has it travelled to, what has it seen and bought

was the latter, seeing how it was packed - it was taped to a piece of cardboard in an envelope, no holder, just TAPE directly on the coin! Yikes!
A quick dip in acetone to remove any unwanted gunk from tape, etc.
Quite worn, but VERY difficult to find in any condition, so I'm happy, especially since I got it for about $20AUD incl shipping (about $18.50US or 11.00GBP)!
Definitely a slot I never thought I'd fill, at least in my "$20 or less" Farthing set!

up more often. That may be just timing on my part. I haven't seen enough examples of either type to come to any conclusions.
This, however, doesn't seem to apply to the silver patterns of that year, as they seem to be more plentiful than copper issues. I am sure they were saved when the "common" coins in circulation were lost/melted and generally not looked after.
I would like to know, from someone with more experience with these, just how scarce they are (i.e. estimated examples remaining per date type, etc)
I am quite new to these older British coins and finding information seems to be difficult. My copy of Spink doesn't give much in the way of details.
I have attempted to contact Colin Cooke with these questions, but have not heard back yet.
