I happened to be looking up "common cold" on the internet and I found cold.com domain being sold for a cool $1 Million Dollars.  Now this is some ocean front Internet real estate if you can get it, they aren’t making it any more but they are making cold.net, cold.biz and cold.us but not cold.com.

High Value Domain Names

Cold.com is one of the few high value, 4-letter .com domain names to be put up for auction recently. High value domain names that have sold for at least US$1 million include: Fund.com at just under US$10 million (topping the list so far for 2008); Diamond.com and Business.com, both US$7.5 million; AsSeenOnTV.com, US$5.1 million; Vodka.com and CreditCheck.com, both US$3 million; and Rebate.com, US$1 million. A list compiled from public sources of the 30 high value domain names that have sold for at least US$1 million can be found at www.PatentKinetics.com.
