Error Struck Through | Recent strong struck through grease finds

[Bri]

Found a few pretty strong struck through grease specimens on the last brick and a nickel in pocket change I thought were neat.

Thought I would add the 1994 that I found in my pocket change a couple years ago for S&G purposes as long as I was on the "Struck Through" coins.


Thanks for looking

Guess you missed it..but he/she is on a mission to prove there is no such thing as struck though grease

In his/her defense, there are different errors that are similar to struck through grease such as a die adjustment strike where before the dies are set in place, the die setter does a series of tests to see if the striking pressure is great enough to bring up the coin metal in the design on both sides of the coin. These test pieces are supposed to be tossed into a scrap bin but sometimes reaches circulation. They appear to have the same degree of weakness on both the obverse AND reverse sides.

There is indeed a struck through grease error though in which the grease is composed of dirt, grease and metal fragments. I wish him/her luck in rewriting the error/variety book though.

The "die adjustment strike" is a myth. Unless you were there when the coin is struck, it is impossible to establish ultimate cause. There are many kinds of spontaneous press malfunctions that can produce a profoundly weak strike. The vast majority of weak strike in the marketplace are assuredly the result of press malfunction, not press setup.

Ok. Thanks for the correction.

Just read it. That should win a LCR award for "Most Popular Controversy".

Filled dies??

I am pretty new at this, but I thought those pics would be coins struck with a 'filled' die. (Filled with metal that hasnt been cleaned out of the die.) Can you explain why this is wrong?
Thanks.

[Maineman750]

Would be best to start a new thread..but what "metal" would you be refering to ? Loose pieces just laying around would most likely be refered to as struck through and leave a pattern or be "retained struck through" examples.

Filled Die

I'm sorry. I didn't know. I just thought that a 'filled die' meant that some of the images and such were filled with some of the planchet metal.
Thanks for the explanation.

[DoubleYou]

Actually these errors are sometimes referred to as filled dies in shorthand to mean that the grease was filling the incuse elements of the die when the coin was struck, so a filled die is an accurate description, although struck through grease is what we typically call it. It generally isn't filled with metal, however. So we might define these errors as coins that were struck through dies that had some grease filling the recesses of the design.

Nice examples. I got a bunch of rev greasers this past week maybe I'll post them tonight when I get home
