Please explain why the 1806-07 pennies are considered the fourth issue

[SilverAge3]

Something I never quite figured out is why the George III penny 'fourth issues' are named thus? What am I missing besides the 1806-07, and cartwheel issues, other than several silver maundy issues? Or is it a scope larger than pennies, referring to SOHO issues, more generally?

Thanks for helping set me straight.

George III coppers are divided into 4 discrete types by design. 1st issue comprises the halfpennies and farthings 1770-5 (no pennies) not struck in a collar; 2nd issue is the 1797 pennies and twopences (no currency halfpennies or farthings) - the 'Cartwheel' issues; 3rd issue is the 1799 halfpennies and farthings (no pennies) and 4th issue is the 1806-7 pennies, halfpennies and farthings (both with different portraits and reduced weights due to the copper price increase during the Napoleonic Wars).

Ok thank you, so it is beyond the scope of just pennies. Much appreciated explanation.

Indeed - the first pennies were 1797 cartwheels - nothing before or after until 1806.
