The Amazing 1974-S Aluminum Cent!

I’ve not heard of that one. I wonder if/when the mint will decide to be the devil and confiscate all the aluminum cents?

Interesting that it's only a uniface strike.

I wonder when how soon before this starts making the "strike it rich from pocket change" YouTube rounds. I guess we'll know when the "is this an aluminum cent" questions start popping up.

Plausible as an artificially struck "error," like so many other artificially struck San Francisco "errors" of that time period.

Cool error. Why not note on the slab that it is a uniface strike? I’ve seen more characters used on the label than that.
Also, it is a little misleading to call this an “aluminum cent” as this should not be considered in the same class as the experimental aluminum cents of the other mints, to which that term lends itself. No doubt, it is made out of aluminum, but struck on foreign aluminum planchet is more appropriate.

I still like to read about this type of coin

Agree. The dealer's description is a bit of hype.
Since there were "aluminum cents" that were purposely struck in 1974, the description he uses is a bit misleading, and perhaps intentionally so. This is a wrong/foreign planchet error.

That is an interesting error.... There are some fakes out there... but some authentic ones too....Cheers, RickO

1974 and aluminum is interesting because I don't think any of the Mints are in the same class with each other.
It seems like:
- the Philadelphia coins were official
- the Denver coins were done unofficially, but how did they get the planchets?
- the San Francisco coins were done unofficially using existing foreign planchets.
Mint Error News calls it the "Unique 1974-S Aluminum Cent" which PCGS calls it "On Philippines 1S Planchet".
I think it's certainly a more interesting coin to think about what Mint employees were thinking about and doing with aluminum cents in 1974 especially since both the Denver and San Francisco pieces seem unofficial, though different.

Being struck on an undersized planchet seems to negate the comparison to the trial pieces.

Just to clarify things:
I spoke to Fred Weinberg after I purchased it, and it will be re-submitted to PCGS for a new tag. Fred is adding a second line.
It will say:

The 1971 Cent that was certified by NGC AU 58 says Aluminum on the tag. It also was struck on an aluminum foreign planchet.

I wish RC would post a photo of his coin in the PCGS holder – it’s possible it struck on a foreign aluminum
Planchet, and labeled as such.I don’t recall hearing of one discovered in a Proof set,but It’s possible – easiest way to clarify the last few posts would be to see a photo of the coin in the holder to see how it’s labeled so we know what we’re talking aboutRetired Collector & Dealer in Major Mint Error Coins & Currency since the 1960's.Co-Author of Whitman's "100 Greatest U.S. Mint Error Coins", and the Error Coin Encyclopedia, Vols., III & IV.

Fred - Yes the coin was struck on a
Nepal 2 paisa planchet. It is at least
99% the same size as a Lincoln Cent.
It is really cool .It is Also a cameo . In 1974 the US mint
Was producing coins for Nepal.
If it wasn’t struck on a foreign
Planchet it would be illegal to own.
That was why the 1974 D cent was confiscated. It was struck on stolen aluminum within the mint.0 -

Wasn't there a legit aluminum cent that was "legalized" and is also legal to own? The one the Congressman gave the janitor?

Using prior case law of the mistake of selling the moon dust bag and the export license mistake of the 1933 double eagle Farouk specimen, it seems like the government official mistake of giving the specimen to Toven would be a legit release.
At the same time, I wouldn't be surprised, if the Mint tried to take action if they tried to sell and profit from the coin given their stance on unjustified enrichment. I'd imagine passing it down to heirs or donating it would be fine, e.g. to the Smithsonian, ANS, ANA. It's just that enrichment / profit may trigger action, even if it's ultimately unsuccessful.

I was in Fred's office. We did some business and he was kind enough to write a submission form to add "Aluminum - Uniface Reverse" on the PCGS insert. I just picked up the coin at the PCGS show in Vegas. They put on a wonderful show.

Somewhere, there's a 74-S indent (although dateless) that was struck through this planchet. The intent may have been for them to bond after being struck, but they didn't.

Mike Byers Mint Error News – Unique 1977 Lincoln Cent on Aluminum Planchet

This Unique 1977 Aluminum Cent is either an intentionally made Mint Error on a leftover
aluminum planchet from 1974-1975 or a pattern struck in aluminumThis unique 1977 Aluminum Cent, struck on an aluminum planchet with a weight of 1.04 grams, was discovered and certified by NGC.
There are several possibilities as to how this unique Lincoln Cent was produced. It could have been an intentionally made mint error. It could have been struck on a leftover aluminum blank from 1974-75 when the United States Mint in Philadelphia struck Aluminum Cents. Or it could be a unique and unrecorded pattern struck in aluminum. Regardless of the circumstances, this is a unique and enigmatic Lincoln Cent.
There are no authorized U.S. coins struck in aluminum for circulation. In 1977, Lincoln Cents were composed of 95% copper and 5% zinc. Since 1982, they have been composed of 97.5% zinc and 2.5% copper.

https://coinweek.com/coins/error-coins/mike-byers-mint-error-news-unique-1977-lincoln-cent-on-aluminum-planchet/Great link and coin! Love the discovery!
Given the following, I would have some concern about owning this:
There are several possibilities as to how this unique Lincoln Cent was produced. It could have been an intentionally made mint error. It could have been struck on a leftover aluminum blank from 1974-75 when the United States Mint in Philadelphia struck Aluminum Cents. Or it could be a unique and unrecorded pattern struck in aluminum.
It may be safer to own since the weight doesn't match the 1974 and 1974-D cents which both weigh 0.93 grams. This weighs 1.04 grams.
This is from PCGS:
Paul Gilkes wrote:
PCGS's examination of the 1974-D aluminum cent during the authentication process determined it weighs 0.93 gram, the same weight as a 1974 aluminum cent certified by PCGS in 2005One exception I would take with the article (and this is perhaps marketing), is that I personally don't feel it's greater than the 1974 issue as suggested (given the presented information) since the 1974 issue is an official, non-error, pattern issue.
As spectacular as the 1971 and 1974 aluminum cents are, they do not begin to compare to this unique 1977 aluminum cent struck at the Philadelphia Mint.

Since we're talking about something that could be an "on-purpose" or "shenanigan" (i.e., intentional error), I need to ask if there is any sign of a Japanese 1 yen undertype.

I was referring to the SF 1971 and 1974 in the previous paragraph.
I just clarified it by adding the S mint mark after 1971 and 1974.
