Ценность старых советских пластинок, как определить редкую

The Buchanan Brothers were two brothers, Chester and Lester Buchanan, who recorded country music during the 1940s on the RCA Victor label. They had a top ten hit, "Atomic Power", released in August 1946; this song was also featured in the 1982 movie The Atomic Café. Another song, 1947's "(When You See) Those Flying Saucers", was used in the opening scene of the 2009 animated release Monsters vs. Aliens.

Their releases were under two different artist names: "The Buchanan Brothers (Chester and Lester) Singing with Orchestra" and "Buchanan Brothers and the Georgia Catamounts."
