I really struggle with upgrades! Near impossible most times for me to make a decision between hammered improvements as, in most cases, the replacement coin, never being perfect, will be lesser in some component of the legend or bust...nightmare, as I always feel like keeping the old coin just for the perfect IZA in Elizabeth! I really, really, struggle with modern stuff (G5/G6), as then it comes down to minute spots, Christ, a rolled two of Colin's 1942 farthings around in my fingers for hours, trying to decide which was the most perfect...I probably missed an amazing Liz or bargain UNC halfcrown of G5 on the 'bay, while I was doing that, NIGHTMARE!
