What number does a silver dollar read???

Nothin serious here. I was over at the dog park the other day with the dog and the Quatro, and I started talking to this guy about the detector and what it would do and all and he whipped out a 1900 silver dollar and dragged it across the coil and guess what it read. 32. Wow, I thought it would read a 38 or a 39 because it looked like the real deal and he said it was real silver. What's up with that? Just wondering because I've NEVER found a silver dollar, but I sometimes ignore a 32 when I'm in the parks just to save time, but I'd , sure would hate to miss a silver dollar. I remember the war nickel story and what a weird deal that was. :?::?::?:

I never tried a silver dollar on my Quattro when I had it, but on my Explorer the conductivity number will read lower then a silver quarter, in fact the silver half will read lower on conductivity number too. My silver quarters will read 30, the silver half 28 and the silver dollar will read 27. Now with the Explorer we have the ferrous numbers too and all 3 of these will have 0 for ferrous numbers. If I had a 28 conductivity and 1 or 2 ferrous it is a silver dime, if the ferrous is 3 than it is a clad dime, but a 0 ferrous has been the silver halves.Now i would think this also will hold true for the Quattro as far as conductivity numbers, but you wouldn't have the ferrous numbers to tell you if it is a dime or half.
I wish I had my Quattro as I could tell you more on the numbers.

Thanks Rick. That's very interesting. In fact when the guy in the park read the silver dollar, I think he may have had several different readings that were a little less that the 32 number, so it would match up pretty close with the Explorer II reading. Man I wish I had an Explorer so I could read the ferous readings too. That seems to give you the little bit of extra info in order to tell closer what it is. It sounds like the clad dimes have a higher ferrous because they're "sort of " less conductive than the silver halves. Not sure if I'm right on that one, but it sounds like the higher the conductivity like silver the lower the ferrous number. At any rate, that amazes me that the bigger silver coins read lower on the conductivity scale than the quarters and silver dimes.. What a trip. Well if any of these readings are repetable, they you could still use them to tell closer what you might be digging. I keep forgetting, none of these machines are "perfect" yet, but boy what an advance they've made since the older VLF units in some ways. I'll still take a Quatro over my old varabile discrimination, bounty hunter, any day, although it was ok for the price and the time it came out. Have a good one, and thanks again.
