Before I post better pics, how does one explain the straight line of impressed denticles under a rimbreak to cud, at Stars 12-13 and betond?
-
By the shape of them they look like Brads-and there are a lot of them, all pre-strike. I'll try for better pics. Plus, the brad seen at AM curls the edge

Hello Everyone! Here is a stumper: 1811/10 O-101 struck through debris (mostly pieces of iron brads). One complete brad struck through is seen at the edge on the reverse at AM. Now, at stars 12-13 and betond is a line of denticles which are impressed into the coin. The spaces between the denticles, normally part of the field, are part of the devices, popping out from the field. This continues over the edge beyond star 13.Also, there is a definite rimbreak there and a cud is forming over star 13 (or it very much looks like one is). The edge lettering, though jumbled in places, is there. The coin also appears to be a bit thinner than usual, as about half of the edge lettering shows only halfway..This reminds me of the Unique 1828 12 Star Half Cent Manly Terminal Die State 2.0-it's made the same way, but no negativlely cast denticles were under that rimbreak cud, as it happened with this coin. Any ideas?

Which would back up what I said about how they are made either by a result of manufacture or by intent.
no, it's "Nature Taking Its Course" when it's innocuously placed in a sulphurous environment

For this run of VDBs, anything less than MS64 received an "Uncirculated" certification

Why I LOVE Copper Coins in PCGS Holders! Bought as "VF Details Cleaned". Broken-out, it became evident that something broke the obverse die when the coin was struck: it left an imprint and broke the edge, creating a rim cud at Stars 2-4. All of this was hidden by a plastic bezel in the holder. Now confirmed as the Unique Manley 4.0 Terminal Die State.

CAC too!

"...I don't consider that one toned. I look at it as a red and brown example. Toned ones to me look like they have been heat treated or some other operation has been used whether chemical or heat."
long-term exposure in an old paper/cardboard envelope will "rainbow" brown lustrous Bronze pennies; some original uncleaned Matte Proofs exhibit this -

Not very exciting as a Coin, per se, but Rarer in its moment than any coin here posted: Just received it as change from the corner store

Why wouldn't the federal government seize these if there is no real chance these were accidents?
they DID (for Proof coinage, anyway). Ask QDB how many error Proof coins were confiscated before auction..
the reasoning was that the coins could not have left the Mint in Proof Sets, because they couldn't fin into the holes... -
but, on the topic of: "Can someone also clarify why a Canadian quarter would be in a U.S. Mint coining press?"
Mint employees did a LOT of things: oil pan error Proof coins, etc -

I believe the OP thought one of these were found in change?
However; this was a proof quarter, overstruck on a silver Canadian quarter- OP's coin was struck at the Denver mint, and I believe that's why allmine indicated coin has copper core.
you can see it... he's posted elsewhere

...and the part about the proof coinage turning 'liquid' is horse manure. For a millisecond the surface of a planchet might flow like a liquid but it instantly solidifies. The word 'liquid' in this context is an adjective to describe the devices floating on what appears to be a 'liquid' surface, the mirrored surface.
what can I tell you; it's in the video. Ask Fred.
-
this isn't that video...
-
"That was referring to coins AFTER the 1970's. (And the surfaces may take on a liquid appearance but the coins themselves NEVER even come close to becoming "liquid"."
ya gotta see the video -
what's it weigh?
-
I've been trying to find it... Fred's prominent in it
yes, outside the date range, but it doesn't say anything about the Proof striking except "two strikes", not like it was a 'new' thing

For the 1850- approx 1970 period, yes.
that PBS video (featuring Fred W!) shows us how the Gold & Platinum Proof coins are almost liquid after two strikes...
