Silver Finding Factory

Only on Star Trek perhaps
That would amount to detection on the atomic level, such as X-ray interferometry.
The physical properties of silver and copper are too similar for any remote device to detect save for spectral analysis.

Even if this would work, I think it takes the fun out of it. Like Go said, for many it is not about the silver, but completing sets. And like Metalman says, you'd still have to open it up and sort out the silver from that mass of coins.

I went ahead and moved this to the MD'ing forum .

the box of halves would look like one big piece of metal to the detector ,,like scanning your detector over your stove top ,,even though there are a couple of different metals included in the make up of the stove top all you would get is one basic signal ,,if you take the burners out and set them a few feet from the stove then they would show up as one type of metal and the stove as another ,,the same priciple applies to the halves ,,even if one roll had a silver half in it ,,the roll would show up as one target until the halves were seperated by a few feet then the clad halves would register as one type of metal and the silver half would be able to be seen as a silver half .

if your getting signals and then find nothing in the hole ,,then you either have to practice pin pointing your detector or it is hitting on a mineral like salt or something else .

be sure that you are following the ground balance proceedure correctly , set up a test board and make sure that the detector is hitting and responding correctly to various metals . and then its all just time in the field and practice .

Ahh yes the metal shovel.

My unit also will ring on the lace loops of my boots. I had to learn to walk slower with shorter steps.

I also learned the hard way on the tot lots that the coil on the metal detector will pick up metal below, above and to the side. I kept digging and finding nothing around the jungle gyms and realized the detector was picking up the jungle gym.

These all seem like common sense, but to a newbie like me, I had to go to the school of hard digs.

It has been feeling like spring around here for the last couple of days. A blistering 50 degrees and all the snow finally melted. I may get out this weekend.

As for the original topic, I roll hunt and metal detect and consider them both funny hobbies, I think I still prefer the excitement of seeing that silver edge. Even if the metal detector could distinguish the silver, it would almost ruin the surprise for me. But that is just my thoughts.
Good luck,

Well then just "open" the box and ......and FLING the rolls of halves into the air and kick em' around until they're all spread out.......then take your metal detector and scan each individual roll......if it detects silver in that one roll........then you just have to open ONE roll to find the silver....
Ha Ha LoL....
Yeah.....wish that was all it was.....cause if you're looking for "Proof" coins and "post 2002 coins", and "low mintage" semi key dates........the "silver" thing.....would only be good for "silver"......but on the other hand, if that's ALL you care about, then......Kick em' around!....(no, I'm still just kidding!)

Hey idahogold what part of the state are you in? I'm in Kootenai county.

I have seen a device that will do this, unfortunately, it costs $35,000.
