Wow! That is quite a collection. I bet you could take all those cards and open up your own store!
I can't imagine having a collection of that size. I have around 10K-12K cards total and I think that is even too much. Right now, I am looking to downsize and get rid of the extra stuff/supplies in flat rate boxes.
Very unlikely to be worth the BIN price. If this was an untouched collection, then there is a chance. Odds are this is a collection of junk collections. You could offer me 1000s of collectors choice stars and I would probably not cross a busy street to pick them up for free!
