Question: What is the most valuable single coin you've pulled from circulation?

[SFBayArea]

Out of curiousity.. what is the single most valuable coin you've pulled from circulation or paid face value for?

Mine was a 1921 Peace Dollar I got years ago...
As for best in pennies: 1922 Canadian Penny low mintage
As for best in halves: None more than silver content value ... Never gotten a Barber in 10 years of searching.
(Updated 2/16/10 - did find a 1901 very worn Barber two weeks ago (AG-03))
As for best in dimes: 1927-S in VF condition
As for best in nickels: Don't search nickels
As for best in quarters: Don't search quarters

Notables although not extremely rare or valuable (all circulated)
1892 Columbian Expo Half Dollar
1986-S Ellis Island Half Dollar
1994-D World Cup Half Dollar
1992-S Olympics Half Dollar

1909s penny probably worth 50$?

[AGCoinHunter]

1883 V Nickel no cents. Not worth too much, but was amazed this thing was still in circulation.

A war nickel. Don't laugh!

1938D Walker. I will be honest, not sure if it counts, I paid the teller $5 for it at the window.

Next would be a 70D Kennedy from the tiny bank at Wallyworld.

Actually for walkers.. I've gotten 1917-S & 1927-S in About Good condition before.. but I wish I had a lower mintage Walker like a 1921.. now that's a find

[treasurefiend]

Here is my 1938d in at least Fine condition. When I found it I posted it here and the title was something like "My meager finds" as I found this and maybe a few 40%'rs. Right off the bat someone said check your red book and sit down (or something like that from what I remember)
