The 45 rpm of Tony & The Raindrops on Crossley records (#340) with the songs "Tina / "My Heart Cried" recorded in 1962 is considered one of the rarest 45 rpm of the white doo wop groups.
This recording is present in the lists of rarest white doo wop recordings made by great collectors such as the recently deceased Ed Engel or Bob Diskin and is present in Jeff Kreiter's doowop guide with a value of $ 1500 with the addition to the review of ... 3 know copies???.
Well, right now this vinyl is available on eBay, its condition is not quite or good, but take a look here in case it is of interest to you...
