Sigma Metalytics Precious Metal Verifier

@crazyglue, after reading through some of the old threads on CCF about this device, I've been considering the same purchase so thanks for posting this.

Love mine. Found two phony silver items in my stack.

What impresses me the most is how it can distinguish he difference between .999 and .9999. Australian stuff shows up as .9999. Very cool.

Thanks MontanaCMR, that is good info.


I also don't want to spend money I don't have to spend. I primarily only deal with 1 oz silver world bullion.

I know silver is dense. On a 1 oz silver world bullion, if the weight and diameter are both in tolerance, would be safe to assume it is nearly certain that it is genuine?

I have been thinking about picking one of these up also crazyglue.
My world bullion collection is growing all the time and
I will probably get one as well in the not too distant future.

I finally had a chance to check my coins. Basically, once you choose the metal type and metal purity, you place the coin on the analyzer. It returns a reading in the form of a line within two brackets. The line could be anywhere within the brackets to be an acceptable reading, beyond the brackets should be considered suspect and tested in other ways. Besides center, it goes three places left and right where you are still in the brackets, and acceptable silver value. Out of all my coins, they all pretty much showed up as centered in the brackets or one place to the right, except for 3 coins. One was a 2015 ASE and the other two Sunshine Mint coins. The ASE measured on the inside edge of the bracket as well as one of the sunshine coins, the other sunshine coin was on the outside edge of the bracket. All three coins pass other tests like the silver slide, ring test, and ice test. All three coins were bought from reputable dealers. I'm going to chalk these anomalies up to dirtier than usual silver. Just enough to affect its readings. There is also a mode that you can set where it will return a reading as a number. I have no idea what that means though as the people using this don't tell you what the numbers represent. The analyzer is based off of a range of readings that were set by Sigma. They must have measured a slew of coins of different types to use as a reference for reading the silver conductivity. I've had some .999 coins read closer to the left side of the bracket, just to have it read perfectly on the .9999 setting. Once again, chalked this up to a cleaner silver .999. Silver coated copper coins can give you a false reading. I've heard someone say that testing in .9999 will give you an off reading on your .999 silver but a way off measurement if copper filled. I'm happy I bought mine.

A correction, there are two places to left and right of center and between the brackets.

I did receive all three wands, but have only used the small wand to test my 1/10 oz gold coins. Even though the machine reads through airtites on all my silver, I had to remove the gold coins to read them with the wand.
