Picked this up in Germany at auction and only seen it for sale there at £400 on the MA Coins portal. I was wondering if that is very speculative or in the ball-park. Other sellers on the net all seem to be out of stock and does appear a bit difficult to get, the Proof only has 8,000 mintage.
This is the double thickness piedfort proof and it seems to go for about $650. I'm having this and some other chinse stuff graded at NGC....so interested to see how it turns out.
