selling question for A&G sp's ???????
 

should we wait until an official list is released from Topps, or list them now?

I am thinking that you should wait for official list or write in listing about how you came to this conclusion these are the SPs. Otherwise, how is someone to believe you.
On one hand, you may do well listing now because someone will see all these cards they need for their master set and want to grab the SPs now.
On the other hand, you may not get decent bids because they might not believe they are SPs. Heck, everyone lists SP in their auction title nowadays.

Better list ASAP...Master Sets are already down to the mid-$80s

I just don't get it. Last year's Master's still sell for $100

Then again, maybe hold off until suppy lowers
