Hi Mat, interesting Blanc Guenar. I didn't know anybody else collected this sort of thing. Here's mine, which is a bit different: thicker cross. But yours has more detail.
Not too long ago I got a Cartwheel 2 pence. Needless to say I wanted a 1 pence also and recently picked one one pretty cheap. George III (1760 - 1820 A.D.) Æ "Cartwheel" 1 Pence O: GEORGIUS III D G REX, Laureate, draped, and armored bust right. R: BRITANNIA, Britannia seated left on rocks, holding branch and trident; shield to right; in background, ship under sail right upon waves. Soho (Birmingham) mint, 1797. 36mm 28.34g 6h Peck 1077; SCBC 3776; KM 619.
Inspired by @heavycam.monstervam , I had to add one of these to my World Mint and Proof set collection. 1965 was the last year New Zealand used the Pound Sterling coinage. New Zealand produced this set in a Pink label with a mintage of 100,000 and a Green label with a mintage of 75,000. Both had the same coins, so I din't know why the 2 different labels. A production issue I guess. 1965 New Zealand Mint set, Mintage 75,000
One color is for a normal mint set and the other color is for a proof like set. I don't remember which one is which off the top of my head.
Here's a new pickup for my Unc Hungarian type set 1848-1946: Hungary KM430 1 Krajczar 1848 NGC MS63 BN Copper, 8.65g 26mm x 1.8mm This denomination was minted by the rebels during the Hungarian War of Independence (1848-1849). While this coin is considered to be a two-year type, the issues of 1848 had no mint mark, while issues of 1849 had a mint mark (NB) in lieu of the design under the date on the reverse.
