I was able to win one of over 200 estate lots till someone figured out the secret and now those lots are going for over a hundred dollars each! I managed to get one early on at about 40 bucks. Thought I'd made a dumb buy but these were TRULY Unsearched !
I got multiple silver pieces but I have bought so many 100s of coins in lots I can't remember what came from where but most were probably in the mentioned estate lot
Panama: A 1953 Almost un-circulated looking Cuarto Balboa Silver coin (Among other Balboas of very great quality) France: 1934 20 Francs (silver content) Sweden: 1935 2 Kronor (silver content) Malaya: 1941 10 cents (silver content)
5. Anything from the 1800s usually surprised me and doesn't happen often. I have very few 1800s.
Most unusual was an AH 1272 (1874-5) 1/2 Miscal, of Kwang-Hsu minted under a rebel leader in Sinkiang in the name of the Ottoman sultan. Apparently it's quite rare among the community here too; 97 Numista rarity now.
I know a place here in my country where there are truly unsearched lots, they sell them by the kilo. Of course there are a lots of common coins, but there are some rarities and lucky finds too (with catalogue values):
10 fillér km547 1950 aUNC $30
1 fillér km505 1929 xf+ $25
10 fillér km 507 1940 vf+ $30
$12 CAD in $1 and $2 coins
And a lots of "little" silver coins like Swedish silver öre, US dimes, Russian Empire kopecks and so on.
There was one nice coin, though: Belgium 1901 5 centimes AU. 
The only thing I got out of that was a new country, Latvia penny equivalent coin.
