I'm glad you chimed in. Did I send you an empty one I found? Or am I thinking of someone and something else? I've seen others, too, at flea markets, 'tweeners, though, not as old as the one I think I recall sending you, but older than the one pictured above.
The only thing that chest is missing are pieces of eight and doubloons!

(Seriously, I would be tempted to load that up with fake coins and jewels, bury it, and then accidentally "find" it with my grandsons helping me do some contrived yardwork just to see the looks on their faces! HAHA)
