Ghosting
When the outline of the design on one side of the coin appears faintly, in reverse, on the other side. It occurs most commonly on coins which are relatively thin compared to their diameter, and have relatively high relief. British pennies of Edward VII and George V are particularly susceptible to ghosting. Not to be confused with a die clash or brockage, which can create superficially similar effects.

GPA
This refers to the Grade Point Average of a PCGS Set Registry set. If a set is unweighted the GPA is figured by adding up the grades of each coin and dividing the sum by the number of coins in the set. If a set is weighted (and someday all of the sets will be weighted) then the rarity of the coins is also factored into the equation.

A British gold coin, valued at 21 shillings or 1 pound 1 shilling. The name derives from the region of Africa where much of 18th century Britain's gold came from. The "spade guinea" was the final form of this coin, issued up to 1813 when it was replaced by the sovereign. The basic design was subsequently copied for many British counters and jetons.

Gun Money
Token coinage issued by the exiled claimant the British throne, James II, while in Ireland. The tokens were modeled on the English silver coinage of the day, only they were made of gun-metal (brass), hence the name. James promised to exchange the tokens for silver coin should he reclaim the throne; unfortunately, he failed to do so. The tokens are unusual in bearing the month, as well as year, of issue.
