HELP WITH DATE?

[jog]

Found this some time back but never have been able to get an exact date . To me it looks like 1709 or 1799 not sure. Haven't been able to locate a British Cartwheel Penny for that date. Any help would be apreciated, thanks for looking!

Here's one from 1797, if this is any help.

Without question 1799, only year for that particular George III Halfpenny.
