Fair enough. If you're putting in 11 hours a day 24/7 then you absolutely deserve the good luck you've had. I couldn't / wouldn't do it myself but hats off to you.
Those are estimates at best. Not sure what they're based on? Gouby estimates that the 1946 is rarer than the 26ME. And for example, although the combined mintage of 1918/19 Hs and KNs is known, the figures for H vs KN are only estimates.
It was thanks to Michael's footnote in that - about the 1946 ONE' penny being scarcer than the 1926ME - that I finally managed to get Spink to include it in their Standard Catalogue.
