Johnson Matthey Silver Bar Serial Numbers?

GRANDAM · April 13, 2015 1:30PM

Is there a site where you can look up serial numbered bars and check them out as to date of manafucture and such?

I googled it and did not find what I was looking for.

Thanks, GrandAm

You're welcome guys. It is, and has been an extremely helpful site for alot of people I'm sure.

Site was helpful, Thanks!!!!

My bars appear to be Variety B,,,, 1 of <1,000,000.

What I am curious about is the serial number prefixes. I have some with an A and some with a C prefix.

C prefix are the original ones made way back whenever.
The A prefix are no more than maybe 1.5 years old, when Sunshine Mining (or Silvertowne, can't remember which one) starting producing them.

Current J-M bars are being produced by Sunshine Minting who also makes the planchets for the ASE's.

Does this mean that my JM bars will soon be developing Milk Spots like the Silver Eagles

??? Would you like to clarify the C prefix presumption ?

Not sure what is being asked, you're always so cryptive

The vintage actual jm 1oz bars have no alphabetized serial numbers...

rawteam1 · April 15, 2015 7:17AM

Oh, and how do you know what you are posting about, if you don't know what you are posting about?...

piecesofme · April 15, 2015 8:55AM

I think "way back whenever" can be interpreted in many ways.
For some, it is the series of bars prior to the ones currently being made.
For others, it's the very first bar they made. It's all subjective.

Does anyone have a pic of a 1oz jm bar with c serial ?

GRANDAM · April 15, 2015 1:10PM

The last (2) groups of 5 pcs JM Bars that I have purchased were C-Series from around March 1st & April 3rd both from the same seller who sells alot of bullion on eBay. They seem to weigh good in the plastic and don't stick to a magnet and are the same size, shape and thickness as other A-series JM Bars that I have.

When they were made I don't have a clue. I see A-B-C series JM Bars on eBay.

JMBullion is currently selling JM bars, prefix B that are produced by Sunshine Minting. I've also have seen them sell bars with a prefix A. I don't collect them ... just overpriced silver bars to me.

ok thanks grand am, as i assumed, the C prefix are sunshine minted bars for those who are interested in vintage jm bars...

I ordered one sheet of 20, when MCM had their sheets for sale @ $349.95, and they all have a C prefix. Your assumption is correct. A,B,C prefix 1 oz bars appear to be minted by Sunshine Minting.
