We'll make a variety collector out of you yet!
AO. The term is doubleD die, not double die. It means the die has been doubled. The die-making process is somewhat complicated but I will try to keep it simple.
In years past a hub (with a positive image of the coin) was pressed into a blank die (negative image of the coin) multiple times to make a die. Each pressing of the hub into the die is called a hubbing. In between hubbings the die would be annealed (softened) before the hub was pressed into it again. If the hub and die were not precisely aligned the latest hubbing would create doubling on the die. Every coin struck by the doubleD die will have the doubling and is referred to as a 'doubleD die' coin.
An example of a doubleD die coin is the 1955 DDO (doubleD die obverse) Lincoln Cent. Check out the photo at http://coins.thefuntimesguide.com/images/blogs/1955-double-die-penny.png . (Yes, the file name incorrectly refers to the coin as a 'double die'.)
Hey I plan on getting one of every coin ever made, so you better believe I'll be looking for those doubleD dies haha.
Welcome to the forum AOmonstra! You have quite a task ahead of you, but that is the fun of collecting. You will aways feel the "hunger"! Best of luck.
Really? Then how about loaning me $500K forever?
I treat it like a long marathon not a drag race.
thats boring... mortgage the house, sell the kids and hire out the wife. go for broke! it's more fun!
Explained pretty well here: http://overdate1.3.tripod.com/rpm/
Also there is a OPM (overpunched mintmark), where one mintmark is punched over a different mintmark. (D/S)
I'm curious about the OPM, if the coin is struck in San Francisco and supposed to have an S why would the coin get the D initially under it? They have dies with D in San Fran?
Am I making any sense haha.
Separate names with a comma.
