Authentic Fine Slate Birdstone Rare Drilling Type For Sale

I am offerring a very rare type of birdstone. As you can see it is drilled from each side, both front and back,
and the drilling meets up with similar drilling up from each side of the base front and back.
The base is also deeply concave end to end. A very rare style of birdstone obviously made for attachment .
Finely made and in perfect condition from an attractive banded slate.
Also an unique mound "eye" low on the head. From the unique head and "eye" definitely a slug effigy.
A fine and rare piece to add to your birdstone collection
3 3/8" long, 3/4" wide, 1 1/2" height
