How about a 'Coney-Catcher?

Sourced from Wikipedia:

Coney-catching is Elizabethan slang for theft through trickery. It comes from the word "coney" (sometimes spelled conny), meaning a rabbit raised for the table and thus tame. A coney-catcher was a thief or con man.

The term was first used in print by Robert Greene in a series of 1592 pamphlets, the titles of which included "The Defence of Conny-catching," in which he argued there were worse crimes to be found among "reputable" people, and "A Disputation betweene a Hee Conny-catcher and a Shee Conny-catcher."

Since the term originates in medieval England, your 'rogue' character can equivocate or reject the term 'Coney-Catcher' if you wish as it is a new term at that time.

Alternatively, you might embrace that word and its meaning entirely. It is around this time the idiom of buying 'a pig in a poke' materialises; selling a dead cat in a sack and claiming it is a pig is a classic 'Coney-Catcher' con.

Greene gives other examples in his pamphlets, providing you with plenty of historically accurate (albeit sensationalised) material to develop.
