Well, that is a pretty awesome collection, and yes I'm envious!
Can I make two corrections and an observation on what I've seen so far?
1. The mintage figure for the 1869 only accounts for all pennies minted in that year. An unknown but significant number of these were dated 1868.
2. OMNIUM does not mean a long life - it’s part of OMNIUM BRITANNIARUM meaning “(ruler) of all the Britons”, OMNIUM meaning “of all”.
3. One penny that you may still be lusting after is the ?proof 1926ME that has the non-mule, i.e. 1927, reverse, of which I believe only 1 is known?
