Genoa ,
Antoniotto Adorno, 7th doge of Genoa (1378).
Grosso
Weight: 3.00 g.
Ex Ercole Gnecchi collection ( sold at Auction Ratto, 21th April 1914, lot 1513).
Someone fell for it and the item was sold for £30. Then it looks like the seller has developed a conscience and cancelled the sale.
His reward? A negative feedback with the comment "BUYER BEWARE*!Seller likes to cancel fair won bids! A Very Negative Experience**"
