Do you find fakes that can imitate the cartwheel effect? Thanks!

The acid test looks OK - but it's so darn imprecise. I tried nickels and it turned the acid a very similar color. There was a difference, but slight. Saw you video and tried with some nd magnets I have for model building. They're real! ? Thanks! Most useful YouTube video EVER!!!
Great question. I ... By: SILVERMAGNETSLIDE. on 06 Apr 12, 08:18:12 Great question. I bought the fakes (listed as replicas) on EBAY purposely so I could test them. They cost about 2 bucks. Ebay agreed recently to stop selling replica coins. Yet, there are some still available if you are interested in getting some to play with. It does appear, however, that ebay has blocked/delisted most of them. They will continue to be brought in the country via other means, and i suspect you will most likely see them showing up at flea? markets etc--as I have seen myself.

By: SILVERMAGNETSLIDE. on 06 Apr 12, 08:31:02 James, I'm not sure how the pole orientation works with regard to the round neodymium magnets. i simply? didn't have any when i made this unit.

top notch work! for ... By: ytgv3fc7. on 06 Oct 11, 14:05:15 top notch work! for that nanogram scale I think you'll need a speedometer, a potentiometer, a voltimeter,? some known weights or coins to start with as your base units, & the easy way is pen & paper to graph weight vs voltage, and a source like a battery. Hang from arm at horizontal, apply voltage to restore to 0 degrees from horizontal, weigh coins/etc. Maybe it was micrograms but you can weigh a single human hair on it.
Nice slide!? By: drutter. on 06 Oct 11, 07:19:45 Nice slide!?
testing counterfeit fake Morgan dollars, silver coins, chinese fakes, silver bars etc. Consider this design to be public domain. You can make it very easily. Contact me if you need any more info/help.
specific gravity is ... By: SILVERMAGNETSLIDE. on 06 Apr 12, 08:45:33 specific gravity is problematic. If it's off, sure, you have a fake. The specify gravity of silver can easily be matched by using an alloy of a heavier? and lighter metal together to result in an alloy with a specific gravity that matches silver. That is where you need to test for the unique diamagnetic property of silver. as an afterthought, if you are testing generic silver, try using a moh hardness scale tester. maybe, i'll pick one up and do a video on that method. one more tool!
Finally, I wanted ... By: CrystalHorizons999. on 31 Mar 12, 07:34:20 Finally, I wanted to add that specific gravity machines offer a way to test the coins also. Time consuming, but I am considering being as thorough as possible. You can get specific gravity devices for under $100 that are generally used for rocks/minerals but should work on coins? also.
Thanks for the ... By: Anvilsplit. on 27 Mar 12, 06:59:06 Thanks for the response--I think I had the opposite problem. The magnets I used were high-strength rare earth magnets like yours, but mine were about 5/16" to 3/8" thick. All of my test coins (90/40/Clad) moved much slower than your example. I think the best course for me is to shop around for some skinnier magnets like? yours, and it's probably important to make sure they fit together perfectly as well.
Yes, isn't it ... By: MX3516. on 01 Feb 12, 22:54:10 Yes, isn't it curious how many "uncirculated" rolls of Morgans show up on eBay these days, all dated the same? year, all immaculately clean. How strange it would be for mint rolls of uncirculated coins a hundred years old to be suddenly showing up in such numbers.
yes, some of the ... By: SILVERMAGNETSLIDE. on 30 Jan 12, 21:24:54 yes, some of the fakes are spot on with regard to weight. I've seen another guy ring the coins and plot the response on a spectrum analyzer. The software is free and can be set up with a mic very easily to do testing on Morgans, certain common rounds etc. The resulting plots are very unique to said types. Brilliant and easy idea. Kudos to him for thinking it up.? Just using your ear is no where near as effective unless you are dealing with gross fakes. Good luck!
is there an easier ... By: lagoveride. on 26 Jan 12, 00:29:03 is there an easier way. I like the slide idea, but it would destroy some of the numismatic value on some coins. Currently I am using a scale. Luckily the morgan i just bought off ebay weighed exactly 26.73 grams on my scale. Have you ever seen exact fakes down to the .grams? I dont live near coin shops and I do buy graded coins but sometimes? i like to collect and put them into albums. As for bullion i only trust gainsvillecoins, apmex, monarch, and scottsdale. got any more tips for testing?

Incidentally, I ... By: SILVERMAGNETSLIDE. on 13 Nov 11, 09:40:45 Incidentally, I incorrectly state that the silver coin moves slower due to its being such a good conductor and the resulting more-powerful induced magnetic field. That's not correct. The effect is primarily due to the diamagnetic properties of silver, a property that causes it to counteract magnetic fields in? motion.
I made one of these ... By: Anvilsplit. on 12 Nov 11, 22:07:05 I made one of these ramps out of much thicker magnets and tested it by using Morgans, a Peace Dollar, and Clad Eisenhowers. I didn't notice an appreciable difference--is this because Cu is a better conductor than the material the counterfeiters are using, or is the? thickness of the magnets a concern?
Is it better to use ... By: 950330aa. on 11 Nov 11, 20:22:01 Is it better to use smaller magnets or can larger magnets be used? I was thinking 2x1x1/16! What about the thickness, how does this affect? the pull?
I hope no one says ... By: CorgiDoom1881. on 10 Nov 11, 21:33:39 I hope no one says mine? is fake! It's a 1881 O in brilliant uncirculated. I payed 75$ for it.
The angle was just ... By: SILVERMAGNETSLIDE. on 10 Nov 11, 06:12:18 The angle was just a play on getting a decent speed for the real silver dollars. It was done just roughly, and it probably won't matter too much if yours if off by a bit. Just test it and see what kind of speeds you get with the magnets you are using--that will determine what angle works best for? you. Glad to know you are making one. Let me know how it turns out!
I could never see? ... By: steelhorses2004. on 07 Nov 11, 03:49:54 I could never see? the entire slide at once to count number of rows of magnets so guessed and ordered 100 pcs 1/2x1/4x1/8 magnets off ebay. Figured 3 pcs per row since morgan is approx 1.5" diameter. How did you come up with the angle? Looks to be approx 30 degrees?
Slick tester. ... By: steelhorses2004. on 05 Nov 11, 09:12:06 Slick tester. Gonna make one of these? too. Are dimes too light to slide down?
Also - where'd you get the magnets?

EXCELLENT Silver ... By: SelfGoverned. on 01 Nov 11, 17:53:31 EXCELLENT Silver testing methods!
You suggested using say square magnets, that are? N45+? And I suspect that as a silver Morgan or Peace Dollar are 38mm+ in diameter, that a silver Eagle, or Maple Leaf are also of similar size? Or would one need (2) SLIDES to test those four coins? Or a wider ramp, to also test Eagles and Maples??
This beats the heck outta using testing acids! (The combo, of tests...) You might want to consider marketing these, before someone abroad JUMPS on it!? Best :-) WST
