Coppercoins only lists it as a RPM: 1964D-1MM-020 Make sure to use their formula as it tells me which site to look at
I didn't see a match on Variety Vista.
Wexler no match shown on the site.

How the number systems work. Lets say you have a RPM and don't know what the numbers are because they are sometimes different. If you use the correct formula to post your find, then we will know what reference you are using. So here is your coin:

You see the number on the image, but what do they mean?

Note what each digit and letter mean? When you type in the 'W' in the formula we can see it is a Wexler listing. When you see RPM-100, then we know it is a CONECA number and can be found on Variety Vista. If you see the no space between the date and mint mark or the 1MM, then you know it is a coppercoins number. So using the right formula will help us determine which number system you are using.

Why do they use a numbering system for these. When the CONECA numbers were first formed, there were only one group listing them. With a change of ideas, others split off or formed new attribution number systems? Why? Because of the computer coming into the in, a number system was needed for the computer to sort out the numbers. Coppercoins was probably the first that I know of with this. You can sort 100 numbers of attributions on a excel program and they will all be sorted automatically on that program. It will sort DDO, DDR, OMM, RPMs for cents for you. Put them into lists. Then others started using something like it. DDO-000 or DDR-000 RPM-000 or WDDO-000, WDDR-000, WRPM-000. The number systems don't match each other, but sometimes they post a link on their sites that link the others together. So on the site, they using of formula will help us save time to ID a coin.

Very nice RPM find! It's also a minor DDO that could be unlisted.
