Also have a full playset of Bayou (B/G dual land) which I heard can buy me a new keyboard. 
Ah ah you tell me... I have about thirthy original dual-lands and they're all "FBB" (Foreign Black Border), including a full set of four black-bordered "Underground Sea". So they look like the beta ones and are worth quite some bucks (about $200 for each individual FBB Underground Sea). I think these thirty FBB dual-lands alone are worth around $3K, give or take some (the Underground Sea are the most expensive, but the others are worth quite some money, especially when they have black borders). I was either opening boosters/starter packs and getting these FBBs or trading them or buying them for $5 a piece.
I also have quite some real niceties like Bazaar of Baghdad (which I paid $10 a piece), a real Legends "The Tabernacle At Pendrell Vale", a full set of force of will, a few misprints, a few signed cards. A sh*tload of cards now worth $20 a pop etc.
But no P9s for me... I started playing in 1994 IIRC and back when we were playing with friends some were playing with P9's without sleeves ! It was just normal to see first turn mox + dark ritual or black lotus + Juzam Djinn and then timewalks, ancestral recall etc. ; ) We were playing the forbidden cards anyway (like Chaos Orb). Library of Alexandria was everywhere. Ah the trip down memory-lane ; )
My friends invested much more than me, they were buying moxes for $100 a piece and lots of people were calling them crazy. They later sold them all for the price they paid them. Now it's what, $1000 for a mox?
Maybe I *should* sell the whole lot and buy physical gold and then buy back cards once the economy shall crash or after the Mayan calendar switch to the next cycle but whatever: I like my cards and it's not about the money.
Now regarding P9s I've read in the past here on GH about some GHers owning some of the P9s...
Nice alpha Sol Ring OP btw ; )
