Main Panel 1: Baldy and Shorty are sitting at a tavern table, startled by the sack of copper coins that is landing forcefully on said table.
Mysterious Man: I'VE HEARD TALES OF TWO MEN WHO'LL KILL ANYTHING FOR 2 COPPER PIECES.
Main Panel 2: We see a shot from below, about the height of the seated Baldy and Shorty, of the mysterious man, who's hit by the sun going through the tavern doors such that you can't see much more than a silhouette. He's tall and somewhat gangly, and the flight suit he wears is a little baggy. Besides the silhouette, which would have him doffing his helmet, we should see a glint off the watch on his left wrist.
Mysterious Man: THAT ABOUT ENOUGH COPPER TO MANAGE... OH, 7 OR SO GIANTS?
Inset Panel: Baldy looks closely at one of the copper coins, revealed to be an American penny dated 1956.
Baldy: CAN'T SAY I'VE SEEN THIS MARK ON ANY COPPER COIN I'VE COME ACROSS.
Main Panel 3: We see the mysterious man, now visible, panicked and desperate, talking to Baldy and Shorty while leaning on the table, which still has the large sack of pennies on it. His flight suit is tattered, and his facial hair suggests he's been wandering this medieval world for at least a week or 2.
Mysterious Man: WELL. I COULDN'T SAY I'VE SEEN A HORDE OF GIANTS IN ANY MEADOW I'VE COME ACROSS BEFORE THIS WEEK.
Mysterious Man: THE ONLY THING I KNOW FOR SURE RIGHT NOW IS THAT THOSE COINS ARE REAL COPPER!
Inset Panel: The mysterious man grins nervously.
Mysterious Man...OR AT LEAST THE CLOSEST THING TO COPPER I HAVE ON ME RIGHT NOW.
Main Panel 4: Baldy looks at Shorty expectantly, while Shorty holds one of the pennies.
Baldy: TEST THE COIN.
Inset panel: Shorty tries to bend the coin with his teeth. It does not bend.
Inset panel 2: Shorty puts the coin back in the sack.
Shorty: IT'S SOLID ENOUGH FOR ME.
Main panel 5: Baldy and Shorty get up from the table, holding their weapons.
Baldy & Shorty in Unison: WE'RE ON THE JOB!
