well there is one i'm focusing on b//c of it's age.... i thought hunted out until i found a 1967 qtr down about 3-4"... that should mean there is still 'some' potential there right?
With no unnatural ground changes and normal lawn conditions a 3-4 inch quarter has most likely been in the ground for 15 to 20 years.
Since 3-4 inches is where many coins stop as ground hardens under them and density is a factor in the settling of a coin, along with root activity from the coverage above, they slow the rate of settling at about that point. Most parks, honestly were picked clean of the coins in that range 20 years ago. The great silver rush was around 1980, after National Geographic had an article that estimated the amount of lost coins from circulation somewhere in the billions range. This was based on mintage, coins in circulation at the time and a few other statistical details.
About the same time, VLF detectors came on the market that could hit the 6 inch range and had some discriminatory circuitry previously unavailable. The volume of coinage coming out of the ground at that range then, especially nice old silver, was astronimical compared to today's pickings and the old timers of that day did not let very much ground go unhunted. Especially since all this was coincidental to a huge spike in silver prices and the rise of the RV market.
Ah yes, I remember well the hordes of retirees spanning the plains in their early Winnebagos with their Compass and early Whites and Fisher machines in high esteem. Fate dealt us a cruel hand indeed. Born into a time of superior technology with comparatively lower potential, tears welling in eyes as I type.
Hey the oven timer went off, the brats are done, gotta go.
