It is…but it’s totally unnecessary I think to see the tone carelessly removed from the high spots, especially for a coin of such prestige!
I see it all the time on lesser coins, where I can imagine someone has ‘pulled’ a coin across a surface to pick it up, rather than ‘hook’ it up (more difficult to do with hammered, of course).
I discovered, quite by accident, that one of the worst offenders is the grey ‘neutral’ boards that come with cameras nowadays, they are comparable to 1000 grit sandpaper when a coin is dragged off it. Many coins are horribly scarred this way (I attach an example).
