You’ve got to be kidding. A 1.5B$ gadget and all it carries is a lousy 1909 penny. Oh, it’s a VDB (I have that) but even they could afford the more rare S.
For the price of Curiosity you’d think they could splurge for a $20 gold piece, even a 1993 Double Eagle we have stashed away. Why not a share of Apple stock? Even a T-bill (by the time we could retrieve it and cash it in I would maybe be worth 1.5B$, like the deal of buying Manhattan Island for $18 in beads).
Or I’m sure some defense contractor can manufacture a special coin, but you know, like $70,000,000.
But even better I vote for sending faux-penny pincher Ryan up to go retrieve the penny, so he can balance the budget – about the same kind of voodoo math the Repugs are selling anyway.
