help wine price

[PortAh]

I have this thought, though very unlikely considering
the price(usually < $40)
when I bought it and time in my cellar(1 to 2 yr),
that I may(without knowing)
open up one that happens to jump up in price drastically.
(please let me know if it will never happen so I dont need
to worry about it :-))

so here is the list, appreciate if someone
can tell me the current price.

91 Grgich Hills Cabernet Sauvignon Napa valley(not Yountville selection)

94 Penfolds bin 389 cabernet shiraz

96 Buena Vista grand reserve carneros Cabernet Sauvignon

92 Robert Sinskey Reserve Merlot(Los Carneros of napa valley)

94 Beringer Knights Valley Cabernet Sauvignon

94 BV Georges De Latour Private Reserve Cabernet Sauvignon


Thanks.
