Watch List notes:

Great Britain, 20 pence, Elizabeth, 1998, NGC Mint Error MS 65, struck on foreign planchet. KM-990. 2.72 grams. Fascinating error with truncated seven-sided design struck onto a smaller round flan (about half the weight of a proper flan) for some other country's coinage, deeply lustrous and light gold in color, with light discoloration behind head, possibly unique.
($100-150)
