Grails II by Proof Collective - to sell or not to sell?

We have been airdropped Grails II by Proof Collective. https://opensea.io/collection/grails-ii-mint-pass/activity

The Floor Price currently is >3.69 Eth with 331 Eth volume. The Pass grants us a reveal of Season II of the Grails, which will be a draw from 25 different artists. Some of these works can sell for >10-80 Eth (looking at the Grails I that were issued previously), whilst others may be duds that sell for less than 4 Eth.

For reference, see Grails I here: https://opensea.io/collection/proof-collective-grails

We have until August 16 to decide, otherwise, the Grails II Pass will be burned. Should we sell or should we keep the pass and reveal the Grails II art?

The artists forming part of this drop are not all revealed, but may include major artists like Tyler Hobbs (Generative artist creating the Fidenzas) and other heavy weights like Grant (https://twitter.com/GrantYun2?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor) and perhaps Drift (https://twitter.com/DrifterShoots).

Of course this is all a lucky draw as well. Here is some of the math:

• Mint pass was airdopped to 1,000 wallets holding a PROOF Collective NFT and up to 176 wallets holding a Grail Moonbird.
• Artists will also be gifted their genesis mint (25) and one additional mint (25 × 2 = 50)
• There are 2 honorary PROOF memberships
• PROOF will also mint one of each (25) for their collection and gallery
• theoretical maximum is therefore 1000 + 176 + 2 + 25 + 25 + 25 = 1,253 across all artworks.
