1990 Fleer -- Unopened Basketball Boxes
 

I've got a bunch of these unopened boxes...what is the going rate these days?

Like 250 on eBay and even more if it had the magical bbce shrink wrap.

Boxes
 

So, people can mail their boxes to BBCE and they shrink wrap them and send them back? How much does that cost per box? I think I have 9 boxes.

per bbce website:

The charge for authentication will be 8% of the retail value of the box (minimum charge will be $8 with a maximum of $5,000). The charge will be applied whether the unopened box is deemed “good” or “bad”. If the box is deemed “good”, it will be wrapped in our shrink wrap with a sticker identifying the box.
For rush services, the charge will be 15% of the retail value, with a minium of $15. Please write "RUSH" in bold letters on the outside of the package.
Please note the customer is responsible for shipping charges both ways.
