Different dies from same mintmarks in same year?

[srevoredo]

Hi everyone.
My name is Sergio. I'm from Argentina.

I started collecting coins from the US a month ago and I noticed that there are different dies for the same mint marks and for the same year, for example in Dimes.

Is there any information about this? Is this consider a variety?
thank you all for your time.

Every year , several dies a year were used at every mint. That’s probably every mint in any country. Never heard of a mint only using one die
Impossible to make 100s of millions, even billions of coins, with a single die.

It is not a variety in the sense of being collectable, but every die might be a little different when the used to punch the mint marks by hand. That stopped in the 1990 time frame.

As Klocc said, there are many dies that are made for coinage in the USA. I do not have the numbers in front of me, but I remember seeing papers that gave the average amount of coins a die would strike before it was retired. I remember that the USA state quarters averaged about 325,000 quarters before they were removed from service.

On average I want to say they made close to 400 million quarters per state, so that means for just ONE type of quarter, they probably used more than 10 dies, probably closer to 15 to 20 total for about 400 million quarters. Here is one site listing the 50 state quarter mintage, and in does vary alot.

Varieties in coin collecting are Doubled die obverse, Doubled die reverses, re-punched dates, over dates, mis-placed dates, re-punched mint marks and over mint marks. A website like

http://varietyvista.com

can show you the Doubled dies and re-punched mint marks along with over mint marks. There is also some data about the types of mint marks that were used through out the years.

one other thing. The researchers will identify " pick up points" that are unique to a particular die. The dies themselves go through different stages of use like early die stage, medium die stage and late die stage. As the die progresses thru the die stages, some of these markers or pick up points will change, whether it was caused by a minting condition or, when a worker removed the die, did maintenance on it and put it back in the press. Some of the more common markers are die scratches or other marks to aid in the attribution process.

I don't have the info handy on mintage and total dies used. I will see if I can find it. I am attending a coin show this weekend so any response from me may be delayed.
