I found a mint state example of the two pence cartwheel on wildwinds.com.
A couple of circulated examples can be found there as well.
http://www.wildwinds.com/coins/SE/SE3776.htmlThe auction description below provides greater insight into the history of the cartwheel 'tuppence,'
and another reason why edges of circulated examples are generally afflicted with edge problems
such as bumps, dings or fractures.
Sale 31: The Pre-Long Beach Auction May 30 - June 1, 2005
Lot 2480Great Britain. Copper Twopence, 1797. George III. Soho Mint.
S-3776. The classic "cartwheel" and largest copper coin ever issued
by Great Britain. Never, before the innovations of Boulton and Watt
at their Soho Mint in Birmingham, had anyone managed to strike such
a massive coin of nearly pure copper, inside a collar that contained
the coin and in effect created an anti-counterfeiting masterpiece.
Russia's big coppers come to mind as similar coins, of the same era,
but they are crude by comparison, with far different and less
effective edges. This coin is quite literally the ultimate
numismatic expression of the triumph in metal of the Industrial
Revolution in England. It was struck just one year in this style
(though in 1805 patterns were struck of the so-called Third Issue).
Each year, this coin has grown in popularity worldwide for its
distinctive qualities and visual appeal. It was made in huge
numbers, by the ton, and continued in circulation through the
Victorian Era, when it was in use as "bus fare"; piles were shoveled
each day from trolley cars, accounting for the big edge and surface
marks seen on most circulated examples. This use or circulation
continued for at least a century, and high-grade coins are today
fairly rare. This one is sensibly rated by NGC as a 63 but
underestimated by them for its luster (NGC insert only; coin too
large for slabbing, so it is not in plastic). It's a lovely Choice
Red & Brown Uncirculated, with more than the usual quotient of mint
red luster remaining, though it's mostly medium brown. Sharp strike.
Exceptional. Coins of this caliber, with this much red luster, have
been bringing more than our top estimate in recent auctions,
sometimes a lot more. NGC graded MS-63 Brown.
Estimated Value $850-1,000.
Provenance: The Cheshire Collection.
Realized $2,100
