Well, it was that rare and cheap I felt like having an experiment- it couldn't get much worse!! First thing- heated on a steel plate till 200˚C plus, when the carbonate changes to dark oxide, which is mechanically softer. When it's up to that temperature and the colour changes, the coin is dropped into cold water. The thermal contraction shock makes the black layer fall off. Soft copper tools are then used which won't touch the bronze underneath at all. I have copper brushes made from fine multistrand electrical cable, and stubborn spots can be flicked off with a tiny copper chisel made from a piece of copper wire with the end sharpened to the right state. If needed, contrast of the high spots on a flat looking specimen can be achieved by keeping the coin in your pocket for a bit! And voila!! I know it's all bit past what people like to have happen to any coin, but it was a satisfying experiment- if it was the only F164A I had, it would be in the collection filling an expensive gap......:)

Yes, and lot 122 sold for £475.

I dont know if it matters but Lot 121 was F80 and Lot 122 was F82

Yes - same applies to the Hungarian Denars of the same era - I found 7 in a job lot of foreign coins bought cheaply recently. No reason to doubt their authenticity and sadly worth only a few quid each.

Found it! Great resource for images, but you’d need to know your coins first before it could be really useful. It would be a massive undertaking now that they’re up, but having the class and sub-class on the images would be useful. Edit: Ah, got it...click on the image and you get a nice big write up. Well done, Dave, must have taken ages

I can’t see any specific pages for the Edwards on his website, though, and the FB link is broken. But I’m modern, I’ll track it down

Hi Stu, There are two. His FB page: https://www.facebook.com/pg/Grunal-Moneta-654941368041899/photos/?tab=album&album_id=654945274708175 and website page: http://www.grunalmoneta.co.uk/

Just email Lee at colin cooke Mike and sure he will send them you , as i did have them but cant find it.

"I was looking for this coin for about 3 years and i think this is the best example that I found." You just got to laugh.

I don't think English is his 1st language.

Was the seller hedging his bets?
