The color as shown in the photographs is not normal and hopefully a result of the photography skills - and not representative of the actual coin in hand.
The design high points for this coin are the central jewel in Queen Isabella crown (obverse) and the point where the spinners thread passes over the right leg calf (reverse).
Neither of those show signs of wear - so it's MS-something, lets go with MS63/MS64 due to the obvious chatter and marks.
That said - if this is the real color then its a details coin.
