Spent a half hour detecting the old student rental where my daughter is staying on campus at her University. Within 10 minutes we had two silvers; 1944 Merc and 1962 Canadian quarter. Man, we couldn't even buy candy at the local store with those worthless Canadian coins back in the day when they were common in the Detroit area where I grew up. Looked up the quarter on one site and it said worth approx. $2.50 in bullion value, lol. We would try to sneak all those coins in at the store and hope the merchant didn't notice or didn't care. Sometimes they would give us 80% or so face value. Wish I still had the pile of nuisance coins I had as a kid in my change jar. The yard must not ever have been back filled and the coins were only a couple inches in the ground instead of digging to China for a change. Of course being a college town there was a sea of pull tabs and bottle caps to contend with.
