It was for a long time believed that all that have been drilled / pierced would be not be of any value, the same with rubbed and dinged coins.
I did in the past mainly scrapped certain coins to free up capital to buy others, now at my age I feel that my thoughts have changed.
the volume of ones that you have found on line that are drilled / pierced are being valued at a price that I'd never considered......the 1678 Charles II 3 pence would have only been a few pence 35 odd years ago found at a boot fair, same with the hammered coins I picked up pre internet days, its been a interesting day finding out about the Counterstamp coin that's a recent find again so I'm more inclined to hang on to the affordable unusual...I could be looking for perfect, mint and uncirculated forever.....
many thanks its been very informative. as always.... all the best "H"
