Tomy/Tomica Buddha's Providence Play Set...How Much?

[Super]

Wow...Is this set really that rare and sought after to demand 300,000yen??? Its pretty old with the vintage yellow lettered Tomy and the boy & girl holding hands Logo, looks like a neat set. Could it have been a site specific, Limited Edition release possibly only available at the site of Buddha?
