Apologies, a lost day, yesterday!
Thanks for the image, I can’t find any other REGNA coins on the internet, so really glad to see this one.
Re 29 being a knackered 26…I don’t personally think so, the out-turned ‘shepherd-hook spurs’ on the petals of Lis 26 are very distinctive and not present on Lis 29 (1), even before it broke up (2). That’s not to say these punches couldn’t have been reworked, trimmed, tidied up, etc., to get another die out of them?
Having said all that, though, Lis 26 looks to have held out into the summer of 1567 and still retains its ’spurs’ on your coin, and remained presumably ‘distinctive’ on the 1567 dated coins (LN-d1) too?
