GUEST: I was aware of the voyage of the Challenger, which was the first oceanographic voyage in 1872 to 1876.

APPRAISER: You're surmising this is about 120 years old? It was made 15 years ago. There's a factory in England that makes these turtle shells and sells them openly as reproductions. This is worth in the region of $150.

GUEST: Okay, so I could have a matching pair?

APPRAISER: You could have a matching pair, a set of three, four... as many as you want. (laughing)
