Hello Rommel. Welcome back.

So what? Price is not the tag placed on an item by the seller. Price is the final number paid to the seller when buyer and seller agree --and often that's a long, long way from the starting price! Don't you watch Pawn Stars, Rommel? :) Or at least, did you watch the program back when it was still entertaining? Sellers often imagine that their items are valuable when they are junk.

And sometimes sellers are actually recent buyers who suddenly realize that they bought junk, and now they are hung on it and need to unload it, desperate to recover at least the price that they paid. At that moment, a motivated seller like this feels like a schmuck. And the best thing that this motivated seller can hope to find is yet another schmuck! That's one of the risks in buying on some of these peripheral online markets. Posted prices can be highly misleading. Just remember: the posted price is only a starting point. 

Rommel, you concluded:
"I just wonder what makes this sextant more dear than a lifeboat sextant or Davis Mk 3"

That's easy. Nothing.
