Looks like a normal rock you can find on the beach to me.

It could be hematite. A form of iron ore, which is usually formless and dull. The holes were caused by oxidation, being near the beach. Or maybe it is some kind of old, space rock, tumbled and oxided on the beach. Interesting, thanks for sharing!
