The Gnosjo Hjalper charity, which runs a second hand store in Gnosjo, said it only empties its cash donation milk jars twice a year, and workers emptying a jar on New Year's Eve discovered the "postvaxel" check, a type of anonymous check, made out for 1 million kronor, or $153,253, TheLocal.se reported Wednesday.
"This is huge. ... I can't even explain how much this means," Gnosjo Hjalper store manager Matts Leander said. "Every donation is valuable. But this is unbelievable."
"The first thing that went through our heads was, there must be something wrong here, someone is playing a prank," Leander said.
However, a bank verified the check's authenticity and confirmed it had been written just three days before New Year's Eve.
Leaner said much of the money will likely go toward the charity's work feeding and housing those stricken by poverty in nearby Latvia.
