Since it appears that I live in a cave - I had No Idea what the heck these were so I had to take a look -
Couple of Observations:
Looks like there are about 1300 of these (Transcendents) currently for sale on FeePay
Prices are all over the board
Looks like no one that is selling these actually owns a scanner (really odd) - Everything posted is using cell phone photos
This one (below) currently posted at $9932 (with Free Shipping tho)
Leon - that is a "stereoscope" card Yes? If so then you are 1 old dude
