I was stationed at Kirtland Air Force Base(Albuquerque New Mexico)in the late 70's where my wife and I lived in the older base housing subdivision.The Air Force decided it was time to upgrade everyone's living quarters to newer housing.These older houses were built before the 1940's and now with them being abandoned offered a lot of good coin shooting.The yards were well groomed and I had a new house to search every week for months.(Kind of like a small ghost town)The detector I used was a Bounty Hunter IB 100 (Induction Balance TR).This detector was the latest and greatest and according to the manufactures hype was going to find everything missed by all the other competitors detectors.(Have I heard this before?) Actually the little Bounty Hunter was a great detector.Anyway having so many places to search I never checked my own yard. One day after making a grid search along my sidewalk the detector picked up a faint rounded signal.After cutting a plug and checking in the hole there was still a faint but stronger signal.Taking my screw driver and loosening the dirt around the edges I could see it was a silver coin to be exact a 1927 s Liberty Standing quarter in excellent condition. Finally the other day after checking Ebay its just amazing how much this coin would sell for.So I guess the little BountyHunter paid for itself and a Mine lab.
