I bet you clicked this thinking I had one. Sorry. The 1974 and 74D Aluminum Cents are maybe the most famous modern Pattern coin there is. I was thinking what are some other examples of modern patterns/trials/experimentals with a Pop of 1 or 0? In 1974 some steel-clad cents were also struck with the aluminum ones and to my knowledge none have gone public having any. I also believe that a 30 1975 Aluminum cents were struck and not sure if any survived. In 1970 a few clad Peace dollars were struck. This one is not widely known and again none are said to exist today. Anymore? The world of modern patter/trials are greatly under -appreciated. Edited by hoosiergator 01/27/2016 12:46 am

Doesn't really qualify as a pattern but the 1970 clad Peace dollars that were struck to learn about striking crown size clad coins for the upcoming Eisenhower series. I wonder if all were destroyed under strict supervision or not?

I would say that Pattern has become a very, very loose term but the 1970 clad Peace dollars are one of the biggest mysteries in collecting. The 1964-d Peace dollars are discussed ad nauseam but the 1970 clad are almost never discussed.

The 1974 and 1974-D aluminum cents are not patterns but rather experimental alternate-metal die trials that came close to being adopted due to rising silver prices. More than 1.5 million of the 1974 aluminum cents were struck before such an outcry arose from the vending-machine and copper-mining industries that they were called back in, and the Mint relented of the idea (copper prices also softened). Perhaps 12 to 15 survive of the 1974 Philly issue. I believe you are correct that 1975 aluminum cents were also struck.
The 1974-D aluminum cents were struck to the extent of fewer than a dozen coins per a Coin World article of 2014 (where the writer tracked down the die-setter Benito Martinez), and at least one was given as a nice parting gift to the retiring assistant superintendent of the Denver Mint and it later passed down to his son. That coin is the subject of ongoing litigation.
Best Regards,
George

Back when they were preparing for the Sac dollars in 1999, the mint did a production run to test how well the presses would handle the new composition (how well they struck up, what the required press setting needed to be etc) The experimental production run used 2000 W dies. None of these have ever been reported in private hands and apparently the entire production run was destroyed. We first learned of these from a TV program "Inside the US Mint". As part of the program they were showing how the master hub was created on the Janaver reducing lathe and the model being reduced was a 2000 W Sac dollar! Alan Herbert contacted the Mint about that (since there were no 2000 W Sac dollars struck) and he was told about the experimental production run. Quote: In 1974 some steel-clad cents were also struck with the aluminum ones and to my knowledge none have gone public having any. They were copper clad steel and while none have come up for sale on the open market, they are known to be in private hands. Quote: Perhaps 12 to 15 survive of the 1974 Philly issue (aluminum cent). I believe you are correct that 1975 aluminum cents were also struck. There were 10 to 12 of the pieces that were distributed to lawmakers that were not returned. Only two are definitely known today, the one in the Smithsonian that was foud in a retiring lawmakers desk drawer and sent to the Smithsonian instead of the Mint for destruction, and the Toven specimen supposedly given to a capital security officer by a lawmaker. (The story goes the lawmaker dropped it and the security person picked it up ad tried to retur it to him but was told to just keep it.) There were 1975 aluminum cents struck, the Coin World Almanac gives the number as 15. These were all destroyed. Quote:The 1974-D aluminum cents were struck to the extent of fewer than a dozen coins per a Coin World article of 2014 This is a curiosity because there are NO records of the Denver mint ever being given any authorization to strike ANY aluminum cents. There would also be no reason to. All the testing was carried out at the Philadelphia mint. There would be no reason to have test strikes made at the Denver mint as well. Interestingly although the government has been involved in the courts trying to recover the 1974 D aluminum cent they say they never made, they have taken no such steps to recover the Toven 1974 aluminum cent which they DID make and which they say is their property.

The 2000 W Sacagawea dies were for the 22k good versions that flew on the Space Shuttle.

If word got out that some one knew where one was they are not going to say in fear the government might take it

Someone posted on here last year that the Mint has recently wasted a few million taxpayer dollars on experimental compositions to replace the nickel to restore seignorage to that series. The article did not go into specifics of what alloys were used (bronze was mentioned in passing) and I can only assume that these were all destroyed.

I have one of these desired gems that everyone thinks does not exist! If anyone would like to see a pic of the real thing just message me! Love some knowledge on it too and its legality as of 2016?

How much would a 1974 p silver one cent trial strike aluminum penny weight? 3.1g?

I assume you mean what would a 1974 aluminum cent weigh. About .9 grams.

Just out of curiosity what would the copper clad steel weigh in at? Curious if its close the weight of a normal copper penny less/more.

Probably somewhere between the weight of a zinc cent and that of a copper one.
Steel has about the same SG as zinc, copper is greater. So a complete steel cent would weigh the same as a zinc cent (and this is correct the 1943 teel cent weighs almost the same as today's zincoln) so the copper clad material would weigh more than the amount of steel displaced. On today's clad coins the clad layers make up about 50% of the coins volume. So some rough figures would indicate that the copper cladding would weigh about .16 grams more than the equivalent amount of steel. So a 1974 copper clad steel cent should weigh around 2.66 grams.

No matter what variety of Stainless I don't think it would be too likely to exceed the SG of copper. My figures were based on the mild steel used in the 43 steel cent. So you could probably accept my figure as a low figure and the weight of a copper cent as a maximum figure.
