Thank you for that. And to enlighten further, I have (I believe) all the mana rocks. Sol ring, Chrome Mox, Mox Opal, Mana Vault and Lotus petal. My other thoughts were I could have them graded to further the aid of sale (or increase collection value) and or I could put them in a custom acrylic coffin display with the five. Do you believe its more difficult to sell the mana rocks as a set, or more enticing to a collector?
Also have aeither vial, which has quadrupled from when I purchased it. As far as holding forever, I remember when a mox was $20 =/ =/ but I was also a tween and poor. lol
