John, I've got you beat---I'm 58 years old and feel 91 this week, but maybe if I got my "you know what" out there in the detector field, I could drop that number down to 81 or maybe 61, if I really tried.:| That Playtipus coil, really sounds great. I like the idea that it's a bit smaller than the 15" WOK, that I'm considering, but has that eliptical shape. That seems to make a lot of sense, not only to get into some tight spots, but in a sense, it might even cover more ground per sweep than a strictly round coil. I'm not sure about that, but in theory, it might. At any rate, sounds like a great coil.
As far as the gold coin, I'm not up on the No Motto, but wondering if that's an indian head also, or some other kind of gold coin. I used to collect coins, when I was in my teens, avidly, and I loved it. That's probably why I got into metal detecting, because you can't find those old coins any more in your change, (hardly ever), and it's sure fun to try and find lost, burried ones. I hope you can get a reading from someone on the $10.00 piece. You know this gold is so funny, because I've "read" several friends, gold rings, necklaces, nuggets, etc, with my Quatro, and got different numbers on most of them anywhere form a 7 to a 19 on a friends mixed gold ring. I guess the "gold gods" aren't gonna let us find this stuff without really "working" for it. Marc.
