I found this coin in concrete! [решено]

Hi all, I wonder if you could help me identify this coin. I found the coin in the road where someone had filled a hole with old crushed concrete bits. It had clearly been mixed in the concrete and had been there for some years. It appears to be a Netherlands coin, the lion and sword appear to be relevant to the Netherlands however, this coin has no edge with writing and it is only single sided, the pressing clearly showing through. I think it may be bronze and it weighs aprox 3 grammes. It's aprox 7/8th of an inch or 22mm in diameter .
I hope you can help, thank you.

Perhaps an old button?
