Found this one CRH and need input on if this is a RPM or not. I did not find a match on VV, but it looks like an RPM to me. All input is welcome. Thanks!

What do the numbers in your title mean?

@John. Greasy is pretty close. I basically serialize any coins I keep or investigate so I can uniquely identify them. That way I don't confuse this 1971D Kennedy with any of the others in my collection.
The first part is the date I started working with the coin (yyyymmdd). The first coin from that day is -001, the 2nd is -002, and so on. This is the 2nd coin I investigated on January 17, 2020. It also helps me keep my pictures organized. I rename the pictures accordingly (20200117-002 Obv full, 20200117-002 Rev full, etc). This keeps me from posting the wrong pictures by mistake.
This is probably overkill, but after a few days I find I confuse coins with each other and forget why I started investigating them. This system allows me to quickly reference my notes and keeps me from constantly re-evaluating coins to remember what makes it unique. I also find this system especially valuable when selling on eBay.
Thank you all for the input on the Machine Doubling. I am putting this one back into the spend bucket.

@ Chris...great way to stay organized...do you write the #s on 2x2s or do you wrap the coin in paper with the #s? Because I find myself checking some coins over again..need to implement a plan like yours....

@GF - If I am still investigating a coin, I will wrap it in paper, or put it into an envelope and write the number on it. If I decide to keep a coin, I put it in a flip and write the number on the flip. In addition to not checking the same coin over and over, this also keeps me from photographing the same coin repeatedly. I can just search my coin photos for the serial number. I am glad you found the idea useful. #128526;
