This in my view is an appalling example of coin-grading and a classic illustration of why a grading-system designed for milled coins cannot be fairly-applied to hammered coins with any wear on them, not to mention clipping! Furthermore, even applying US criteria for milled coins, AU55 should be for a coin showing full detail with light wear and a significant amount of remaining lustre, I cannot see how NGC evaluated this at such a grading. Where are they coming from??
