MS-60
Gold coins are softer than either silver or bronze coins.
For this reason, they ding up more then either of the other metals.
Thus it is possible to have no wear on the high points of the designs of them, and yet on average, have more dings and scratches at equivalent grade, than for the other metals.
Some are more inclined to downgrade gold coins with the same amount of wear because of the softness of gold.
I would expect to see grade opinions in the range of AU-55 to MS-61.
I would agree with the OP's comment
"Not perfect, but not too bad".
