When did reeded coins shave?

Excuse me, but could you please clarify what you mean by 'reeded coins shaving'? Are you referring to the historical period when coins with reeded edges, or milled edges, began to be produced? Or are you asking about a specific process or event related to the shaving of reeded coins? If the latter, I'm not immediately familiar with a widely known instance of reeded coins being shaved. Could you perhaps provide more context or elaborate on your question?
