Pawn Stars - Season 18 Episode 7

A seller shoots for the moon, when he comes in with some Apollo 11 documents. Can Rick bring him down to earth before we have a problem? Then, a Harley Davidson 1962 Topper scoots into the shop. Can Chum get the bottom price on this bike? Next, Rick checks out a Renoir etching. Will it make a real impression, or is it too abstract? Finally, the stakes are high when the guys leave the shop for a little friendly competition. Will things get hairy for Rick, or scary for Corey?
