Appreciate your desire to give us first dibs! Still, the best place to determine fair price is on ebay with recent sales. If you ever sell on ebay, you have a seller's account and, with that, you can get more specific history such as the actual price paid for best offers, and longer history (3 years) which is helpful if it is a rarely sold items. Then once you have the price, you can decide if you want to adjust it down a bit to help sell it faster, etc. Also, keep in mind that ebay takes cut of like 10-15% so if you sell elsewhere, you can offer a lower price and still come out the same. But don't forget the PayPal fee of about 3%.
If you don't want to do all that leg work yourself, you could have someone else do it for you for a cut of the profit, or in exchange for pins, etc. There are folks out there (myself included) willing to do anything from help price it to take care of the entire selling process.
You could also consider just selling all of it to a reseller or another collector interested in acquiring them all. That would likely be your fastest path but least profit since the other person will likely want a deep discount for taking everything (especially if they are a reseller).
Good luck regardless of which way you go! And I look forward to seeing your sale.
