Note that presence of a fin (called a wire rim or knife rim by Breen) is not an indicator of the use of abnormally high striking pressure. According to mint documents it is a defect caused by mismatch between planchet diameter/upset angle and the die.
As far as the rest of the stuff mentioned, see previous very skeptical comments on “branch mint proofs,” lunar green cheese, and a face on Mars.
PS: I was wrong and all the documentation was wrong – there are branch mint proofs. I just found a complete set! They are dated “1968” and all have the “S” mintmark. Now that’s settled once and for all!
Well I guess it when it rains it pours (ie the 1821 SP67 bust half).
This coin fetched $3000 in the 1975 Stack sale as a "proof." For that time, a proof annotation with no qualifiers usually meant a coin of lower quality since choice, gem, etc were in use at that time. At $3000 if fetched money that was considerable for the time. My ex-1867-s quarter realized $1800 in that sale and is a $100K coin today. The 1901-s gem quarter (MS67 in 1990) fetched $5500. The 1891-0 quarter in Proof-like gem fetched over $5250 and the 1871 CC 25c in gem fetched $10,000+. Using those ratio's the 1861 SP half is a > $100K coin today. Possibly $150-$200K.
Speaking of 1975 Stack's sales, I have an 1839 quarter "extra long claws" reverse (which wasn't so described, having been officially discovered in 1989) from the Essex Institute sale which was described as "Proof-like surface obverse and reverse. Square edges. This could have been a Splendid Striking".
The "Specimen" classification from Breen was just catching on and I guess the cataloguer must have been confused with the new terminology.

Don't you remember there was a few 1968 dimes found w/o a mintmark?
They were even slabbed....
