1806 British Penny

First of all, welcome to the forum.
Under George III the first copper pennies were issued (before that they were silver). The first design, all dated 1797, was so-called "cartwheel". In 1806 they switched to a more conventional appearance, designed by Kuchler. The coins of this type, were struck at Soho mint in 1806 and 1807. There's a unique example dated 1808 ("probably a proof" - Coincraft Catalogue). A number of bronzed and gilt copper proofs, all dated 1806, were minted for year afterwards at Soho (the term for those coins is "late Soho").
On the obverse king George III, ruled from 1760 to 1820.
On the reverse the figure of seated Britannia.
The mintage figure is unavailable.
That's probably more than you wanted to know about it.

Thanks for the information on the coin and the grading recommendation and that grade was on the flip from the dealer 20 years ago so I just put the same grade on it when I changed the flip two years ago.
