This coin does not seem to exist in a state of conservation inferior or superior to AU.
If you have a more worn copy than the known minimum conservation state, remove aproximately 30 percent for each lower conservation state. In the opposite case, you probably have the best known copy, as long as the coin is not sold, we can not know what price will be obtained in auction.
I classify these coins in two groups because the weights go from 9.50 grs to 17.50 grs!
