1843 Groat 4 over 5?

[VickySilver 775]

I like this near-orphan series and have a decent collection. Some years ago I got this coin by chance off eBay and it may be the somewhat elusive 1843 4 over 5 variety. I confess that I’ve not seen other specimens so it may just be die damage at the datal.  It almost looks like an inverted 5.

4 over inverted 3? He'd have the 3 punch to hand.

I'd say die damage, either manmade or accidental - otherwise it's something over 4 (the 4 being the underlying figure)

I am still trying to figure out the number, and does or has anybody seen the 1843 4/5?
