Vintage Common lot: Best way to move?

[toledo_mudhen]

From what I can see in your photos - most would top out at PSA 6 - Did see some OC and MC - so those would take a hit.

PSA SMR shows the following on the common cards

----------------------------------------5 EX 6 EXMT 7 NMT
Commons 1 - 100------------------------10 15 26
Commons 101-180, 261 - 340-------------10 15 26
Commons 181 - 260----------------------10 17 32
Team Cards: Name Centered--------------15 22 45
Team Cards: Name at Left----------------20 32 65
Team Cards: Dated---------------------- 35 55 85

If you could manage to hit a few 7s - then you win
If the majority come back as 5's then you lose as you will probably end up having around $10 each in grading fees

One final note - I personally prefer SGC Slabs for my collection - I think they grade more consistent and the look is awesome. However the PSA Snobs are not going to want to give SMR value for SGC Slabs. (too much Kool-Aid) So if you are doing this specifically to flip em - then make sure you go to PSA

Hope this helps
