Not exactly the same as hoarding, but it can have the same end effect when a card that was previously thought to be scarce or in short supply is found out to exist in higher numbers. For some post-war examples, see the Gil Hodges Dormand postcard, 1964 Topps Giants (though high grades of those have risen quite a bit lately) and the 1967 Topps Brooks Robinson. The Hodges and '64 Giants were the victims of a stash of cards that were later found and the Brooksie was found to exist in higher numbers than previously thought.
Of those, I believe the Hodges pc find had the biggest effect on price.
