My father passed away a couple of years ago and we're finally starting to get our arms around his coin collection. He dabbled in this on-and-off from the 70s to the 90s before setting it aside. Now I've volunteered to catalog and try to assess the collection's value.

Dad did a decent job trying to organize things but his collection predates the Sheldon grading scale and I'm trying to make sense of the grades they do have (so I can be fair to everyone around what the ballpark values are).

Right out of the gate, I'm diving into the silver dollars - almost all Morgan and Peace dollars - and probably 2/3rds of them have a "CHBU" label on them. I know that stands for Choice Brilliant Uncirculated, and I even found a 15 year old post on another site that offered this rough conversion:

BU- Refers to mint state coins MS60+, but usually the lower end coins (60,61,62)
Choice BU- Usually refers to MS63, and sometimes MS64.
Select BU- I've seen usually described as MS64.
Gem BU- Refers to MS65

but there's other notations on a number of Dad's coins. I've attached 3 examples and you can see CHBU on all of them but they're followed with either a number (65, 125) or letters (AI)... and there are plenty of other different examples I've found (AW, NJ, IJ, and numbers ranging from 40 to 175).

There's even another box with the coins in protective sleeves no CHBU on them but two-letters handwritten on the sleeve: PD, WD, NW, PA, RW and more.

I'd appreciate any insights or directions anyone can provide. I'm just getting started on this journey, reading as much as I can to get up to speed but am struggling with how to catalog and classify these coins.

Thank you!

to the CCF, blackjak! The labels seem to be from the original seller. It was a common practice for dealers to write various things in code on the holder or label - such as their cost or some such - so that they would know how much room they had to bargain with a potential buyer.
As for assigning a numerical grade, you're trying to convert a subjective nebulous rating from a seller to the Sheldon scale. I would consult PCGS photograde (https://www.pcgs.com/photograde) and assign a tentative grade myself.

Thank you Hondo Boguss! That's a very helpful insight (though the handwriting does look like my dad's which is what threw me... but I could certainly be wrong).

Regardless, I appreciate your pointing me to the PCGS guide. I hadn't come across that yet and it does seem like it could solve my immediate challenge nicely. My thought is to try and figure out what are the higher value coins to then consider getting formally graded if the value is high enough while cataloging the rest.

And, to that point, I'm experimenting with a couple of different cataloging software tools, CoinManage and OpenNumisat. CoinManage has an interesting feature that will provide a value if you can supply the grade. Using the PCGS guide as a first pass, this could be my solution.

Again, thanks for the quick reply. You've saved me a ton of frustration.

You're most welcome, blackjak! And if you'd like second opinions on your grades, feel free to start a new thread for each coin in the grading forum.
