I’ll say this...

I would imagine most collectors that have a signed card authenticated for resale would not choose JSA or SGC. This is nothing against either company but is specifically related to cards. If someone were selling a signed 8x10 photo, resale value would typically remain the same.

For signed cards, I would think the most typical choice for resale would be PSA/DNA or BAS. Modern cards (e.g. Mike Trout signed rookie) should sell for the same amount with either PSA or BAS and some collectors might prefer the Beckett holder. For vintage cards, it is without question (for me) PSA/DNA for resale.

If I see someone post a signed vintage card in an SGC holder on a message board when showing off their collection...I figure it must just be brand loyalty or preference to the holder type. If I see someone selling a signed vintage card with anything other than PSA, I figure it must have previously failed PSA. While failing PSA is of course no true verification that an autograph isn’t authentic, the holder itself holds more weight.

This might not be true for everyone but this is how I see it when determining resale. I use all 4 companies for resale but it is based on item type and tier.

EDITED TO ADD:
This thread shows some amazing work of the members here. While the ffindings are sad and I feel for the buyers, there is always some level of fraud in everything and it must be exposed. Tremendous work and great collaborative discussion on a necessary topic for our hobby.
