Bronzing is done at the Mint, usually on medals but some Patterns and early Proofs seem to have been bronzed.
This 1856 S3 PR66 seems to have been an instance of a CN planchet being bronzed. It is the only known S3 1856 that is Proof, IMO. It used to be attributed as copper (J-181) prior to Stewart Blay having it tested.
I think they took a heated planchet and coated it in a mixture of bronze filings and suphur and then struck the coin. The finished coin is chocolate brown not red.

I don't know much about PF Large Cents, but that just looks like a really nice BS and not a PF.
