I sold a Hawaii vinyl version of Kikaida 01 to a Japanese collector for over >$1000 US.
Kikaida 01 and other Japanese action heros were popular in Hawaii in the 1970s when the shows were broadcast in Hawaii .
Most of the original Japanese vinyl action figures issued in Hawaii in the 1970s are rare as children would trash them after they were worn out or outgrew them (since they were inexpensive). Most were destroyed. This is the primary reason for their high dollar valuation.
