I have a 1986 Spanish 100 (cien) peseta. It is a known variety called busta pequeno or small head because of the small hole in the 6 of the date.What I can't seem to find is any more information about it. Apart from they discovered another variety of this coin in 1988 called busta grande because the lettering on the obverse touched the rim. Anyone know anything more about this, how many were struck during the 1986 minting, scarcity etc I would be grateful
