Thanks! Fanned back. The dragon stands out nice. Looks like The Dragon of Fortune. That, and the celebration dragons bouncing in the new year of the dragon tonight and tomorrow in china. Which makes for perfect timing for this auction!
Almost all 20 cash and most Chinese coins are copper alloy. Which im pretty sure it is by the greenish color after aging. Its like a 20:80 ratio. If copper alloy. Sorry but I dont know much else. I found on a trip to the the great wall. Which I plan on going back soon since a part of the wall collapsed. So expect more old coins in the months to come.
