Sorry but this has been driving me a bit mad!!
I only have one vague scene that I'm hoping will be familiar to someone and I can then put it to rest and identify the film or tv programme
It's set in America in the old west-but I'm not sure if it's properly old west 19th century or modern day but that sort of 'ranch' type area.
People hunting gold. A man is selling property/land in an area known to be a place to pan for gold. He loads a shotgun cartridge with gold specs and shoots it into the river, speckling it these tiny gold pellets.
Prospective buyers than pan then river for gold and find the gold pellets and think the property and land is worth loads so snap it up, not realising the realtor is the one who has planted it....
Help!
