I have a 1966
Red Book (published in 1965), and I use it to calculate the
inflation-adjusted values of coins (in other words, to calculate their
true value appreciation from 1965 to present!).
If you'd asked 'what coins have lost in
inflation-adjusted value', this would have been an entirely different contest!

With one 1965 Dollar being worth about $6.75 in today's money, a coin has to have appreciated 675% in numerical dollar value from 1965 to 2009 (ie. from the 1966
Red Book to the 2010
Red Book) just to have the same 'true' value (that's translatable to purchasing power!) that it did in 1965.
Almost all non-key
Mercury dimes have lost in 'inflation-adjusted' value. The 1916-D has, however, doubled in inflation-adjusted value.

The coins in this contest that have actually lost numerical Dollar value since 1965, well as for what they've lost
after inflation is factored in...

That BU 1938-S Nickel was going for the equivalent of $98 in today's Dollars in 1965!

See, if a coin was worth "$1" in 1965, and it's still worth "$1" in 2009, it's now
really worth about a seventh of what it was worth in 1965.
