I've never regretted my early milled purchases, and my regret is not filling in many type gaps earlier when they were cheaper and I had money To me, their only downside is in the lack of variety of reverse designs. For a hundred years or more, all you got from crown down to sixpence was the quartered arms in shields (ok, there were roses and plumes and stuff like that, but you know what I mean); and on the coppers, just the same louche Britannia. Having said that, we didn't get rid of Britannia on all base metal coins until 1937.
