I have one set of these available only, and doubtful if there will ever be any more as they recently changed them all.
There are 78 colors shown in the 3 scans including the 'Royal Blue' which was withdrawn several years earlier and did not feature in most of these sets.

I will sell the full 78 chip set for $230 shipped
or
I will sell the regular 77 chip set (ie without the Royal Blue) for $210 shipped
and
the Royal Blue on its own for $25 shipped.

Email me if interested.
