In the absence of getting upgrades on coins in my collection , I have now started buying similar grade coins to the ones i have now but with a better tone (colour) , I really love the light coloured chocolate tone on early bronze and copper. Early Victorian bronze is harder to find with a good tone than the copper Anyone think this is a waste of time , or is eye appeal not valued in this country (Unlike the states). IMHO a lovely toned copper George IV penny for example is a real thing of beauty and to be admired a black toned one does very little for me , but I might consider it as a space filler. I sell the spares on ebay - this sort of upgrade usually cost me 20% of the coins value , so it really is not that expensive.
