Hmm, done a little cache hunting - no finding yet, but I've been collecting stories for a long time - some of them might turn out ok - some were made up to start with by some story teller to entertain a gullible audience. Others were found long ago by relatives - not always those named in the will - so they kept quiet and slowly got wealthier. I do agree there are still a lot of caches out there, been close to a few that were recovered - by friends, nothing huge though.
Several from the forties - fifties, two from 1800's and 2 modern ones.
All were found by accident. One was a tobacco tin under a house, not buried - just out of sight sitting on framing, modern 1980's - contained just under 2 thousand dollars in notes.
Other modern one same era was small glass jar behind loose brick contained a couple of hundred in notes and coins.
One of the 1800's was in small tin, buried under a stone that was moved to build a garage foundation, this contained a few gold and silver coins, value in 1990's about $1,000. The other 1800's was built into a wall and found during renovation, was gold dust and nuggets - value not revealed but under $5,000. At about the time this was found I found, also inside a wall, a leather bag - containing carpentry tools and a sandwich (amazing it was still recognizable all dried out and leathery - can't say what was in it but it didn't look too good). I think the builder covered this over by accident. I often wondered who got the blame for "stealing" it!
About ten unopened wage packets containing cash from the 1950's were found in a secret compartment in a large wooden dresser. Some of these notes were sought after by collectors so value was quite good about $5,000.
A large preserving jar half full of bigger silver coins latest date late in 1940's, was dug up when removing an old clothes line post. Never got any indication of value but it would have been under $1,000 when dug, about 1980. Nuggy
