Logo: Letter Y in a circle. Sometimes misidentified as Yone or Yonezawa.
What's it worth? Take a look at this Sanko price guide: sold listings for a value indication.

I am trying to find out more info on the Sanko they use a marking with a y and a circle.. are they still in business? or is it safe to say the toys with this marking are truly vintage..
They seem to be still in business according to this page, however it's difficult to find any info on the company, so it's the question if they still make toys. I did found a Japanese company with the same name producing molds in all kinds of shapes and materials, so that might bee them. I think it is safe to say toys bearing the Sanko mark are vintage.
