All.... thank you for the advice and follow ups. I did contact one AH as I will be close to them when I go back East to visit. I might chat with them next week.
Having said that, I spent some time today really looking closer at the cards and I would say most of the older cards are GD or maybe VG at best. Many are worse than that. Probably not too surprising since they were kicking around in a paper bag

. I am definitely not going to get any card professionally graded... out of principal just not worth the time and effort.
Anyhow, learning lots as I dig into the cards. Here are a few scans I took today of some of the cards people have shown interest in.
- 1957 F. Robinson
- 1957 Koufax
- 1966 Mantle
- 1966 Palmer
- 1968 Ryan
- 1976 Brett
Am I fairly accurate in that these are probably GD to VG at best? Could any be considered EX to VG? Am I over-grading?.... Just trying to get a handle on my estimates as I finish my cataloging. I am leaning towards putting them up on BST and trying to price them fairly. I am not bent on trying to make top $$$, but would just love to give back the community and hobby which brought me so much fun in my childhood. Again, thanks!
