Tokubetsu-kicho
特別貴重
What is Tokubetsu-kicho (特別貴重)?
Especially Precious; the upper grade of the NBTHK's pre-1982 paper system (Tokubetsu Kichō Tōken), issued on green paper ('green papers' in Western collecting). No longer issued since 1982, and largely disavowed by the NBTHK today; many blades with these papers fail when resubmitted. Treat a blade whose only papers are Tokubetsu Kichō as unpapered. Exception: for low-value fittings, a modern shinsa can cost more than it adds, so old papers are sometimes simply left in place.
