Coins

I have 3 Morgan NGC certified coins. There is a ten digit number below the grade. What does this number tell me. How can I tell when these coins were graded? Thanks in advance for any info.

The number is the serial number that identifies the coin at NGC. The first 7 digits are the invoice number that the coins were submitted on. The last 3 digits (after the - ) is the line number that the coin was submitted on. For example, the 15th coin listed on invoice 1234567 would have a serial number of 1234567-015.

 

You can't really tell when the coin was graded, but if you pay attention enough, you can kind of have an idea. NGC uses certain ranges of numbers for invoices at shows (the expensive same day grading), online invoices, etc. You just have to know what they are.

 

The best most people can do is look at the slab itself and see how old it is. The grading services change designs every couple of years. You can kind of tell when the coin was put in that slab, but thanks to reholders, the coin could have been graded earlier.
