I would be much interested in these magical trinkets that reside in the pockets of the denizens of this land, and humbly offer my services in helping you acquire them, <name>.
However, I sadly cannot pay you in the coin of this realm. What I can offer are ephemera - coins of purest air. They're better than nothing, though!
Carry my lamp with you. Drop the treasures you steal within, and I will grant you these coins. Perhaps the former owner of my lamp would have a use for them.
