I do not know much about this type, but here is a well worn Marc Antony Legion VI Ferrata Denarius I picked up a while back. It seemed unusual to me for a couple of reasons: The galley seems to be in 3/4 perspective, versus the "flat" presentation I normally see. At the very tip of the prow, I see a little fleck of bronze or copper. Could this be a fourrée or is there another explanation? If it is a fourrée, I thought there would be more evidence, given how worn it is.

Legio sexta ferrata ("Sixth Ironclad Legion") was a legion of the Imperial Roman army. It probably originated from the Republican general Pompey's 6th legion in Spain. In 30 BC it became part of the emperor Augustus's standing army. It continued in existence into the 4th century. A Legio VI fought in the Roman Republican civil wars of the 40s and 30s BC. Sent to garrison the province of Judaea, it remained there for the next two centuries. The Legion was also known as Fidelis Constans, meaning "loyal and steadfast". It is unclear when this title was given, but several sources indicate that it may have been in the 1st century AD. The symbol for Legio VI Ferrata was the bull. It also carried the symbolic she-wolf with Romulus and Remus.
It does look odd in the positioning of the ship, but I see nothing to condemn the coin. I see the bronze sticking through, so it may be a fouree. Short of cutting off a section, you may never know for certain. My poor example of Leg VI Sexta Ferrata
I think the bronze or copper you are seeing is either toning or deposits on the coin, it appears to be solid silver to me especially given the weight which is in the normal range for solid examples of the type. As far as the strangeness with the perspective, your coin is double struck. Basically it was struck, rotated a bit, then struck again. You can get some really strange looking coins from this process especially with types like this where most were not struck evenly and so both strikes were likely only partial strikes.
RATS! No Legio VI... I need to catch up to @Bing 's cool Antonius Legio collection! Congrats on your cool Legio VI @jb_depew ! You won't go wrong with @red_spork 's advice... he knows the Republican and Imperatorial coinage well!
I would agree that it does not seem to be a fourree. The 'ship-side' does look unusual, but this may be due to a double strike as red_spork mentions. My example of Legio VI Ferrata:
