Chips have seemed to double and triple in value - not in all cases but more of the high end stuff, though we've all seen some of the low end stuff get crazy as well.

Now - is this because they are just sought after pieces, the moon is full, or someone has advance knowledge of the anticipated copy of TCR?

$5 Landmark (book at 800, bid to over 1200 - I bought this chip less than 6 months ago for $600 and mine is in better condition)

Something just doesn't feel right to me, but I'm not sure I can put my finger on it.

Opinions?
