Footnote:
I've just entered values for George VI and almost across the board those prices have increased. It seems his reign has been undervalued and is now catching up. (Mind you, mostly there are only values for EF and UNC - but to compare, Elizabeth II is static.)
Values aren’t everything. Some of us want to handle our coins with care, viewing under different lighting conditions, as nature (or mints) intended, not entombed in scratchable plastic.
