Does anyone catalog all known Wrong Stock error coins?

Neca63

Is there any orginization or group that has a listing of the known wrong stock planchet mint error coins?
I think it would be of interest to classify all of the known wrong metal coins and keep a directory of them.
What wrong size planchet coins exist?
What full diameter wrong stock coins exist?
Of the known off metal, wrong stock, wrong denomination, foreign planchet, and rolled thick and thin planchets error coins, how many are are business strikes and how many are proofs?
What dates and mints occured?
What metals were used?
Is anyone already tracking these, or interested in doing so?
I am not coming up with much in my search efforts.
I really dig the full size wrong stock and wrong denomination overweight and underweight coins.
I respect their ability to stay well hidden, and I enjoy looking at their subtle strike characteristics.
Anyone else?
Thanx

I'll create the database, you input the data....

Lets see who is interested in contributing to the effort.
Someone may already be doing it.
I am interested.

I think you will find it a daunting task.

I can have the database and input form created in an hour or two....... Inputing the data may take a while

Impossible task.

Way too many foreign planchets produced over the years at the us mint.

Many of what you are looking for are unique examples that may sit in collections for generations.

I probably have at least 20 off metal error coins and some, I have no idea where the planchets came from.

Edit: I reread the wrong stock part so that may be doable ... wrong planchets ...no

NECA was started with 3 collectors needing double die information.
Once it initiated, other people became very interested and helpful.
The original NECA Master Files double die database of 143 coins took the combined efforts of a handful of attributors about 18 months to complete..in 1964-65.

Lets us see what evolves.

Would be an interesting data base, but will never be complete.

And not all old reports are accurate. The early Steiner-Zimpher catalogues used to list a 1967 or 1968 or so quarter on half dollar stock, till I wrote them (remember letters with stamps?) and asked if it was 40% silver clad. It was not; it was copper-nickel clad. The listing was changed to rolled thick.

Start with proof and business strike wrong stocks.
Sub group the errors by types of wrong stock... denomination, foreign, and thick and thin rolled.
List the different dates, mints, grades, and prices.
Post photos of them.
Start with only certified coins.
And maybe, only post prices for a given coin if pics are made available?

Seems doable.

Wrong stocks first.
Then, wrong planchets over time as submitted with photographs to a database.

Read all the PDF copy version of Mint Error News magazine as Alan Levy used to track a publish all monthly error sales.

Definately a wealth of information for sure and many thanx to Mr. Levy.

Perhaps a grouping of Wrong Stock error coins could be catagorized and listed as:
Proof
Business Strikes

Then...
Foreign...U.S. ( Mint experimentals and transitionals)
Foreign... Non U.S. (Coins intended for another country)
Denomination...Thick Planchets
Denominaztion...Thin Planchets
Rolled...Thick
Rolled...Thin

May work.

Are we gonna do it?

Lets see if forum members want to start listing their wrong stock errors.
This forum is a good place to start.
If ya got em, please post em.

1) I have a full diameter Choice BU 1937s Merc dime on a thin 2 gram silver planchet.
Not sure of it's actual silver metal compostion.

2) I have a Proof 1988s half dollar NGC PF64Cam thin planchet mint error. 8.8 grams.
Coin is clad composition and weight approximates that of a U.S. clad quarter.

3) I have one of the yellowish 1941 thick planchet cents.
It is Au/Bu and weighs near 3.5 grams.

4) I have an ungraded circulated f-vf 1944s Cent on a thin copper planchet.
I assume it is on a foreign planchet.

Anybody else?

Start up a website and accept submissions. I only have a few of them right now but I have sold quite a few over the years.
