Probably not much value at all.
Ever since the Euro's came in, most foreign coins (even the older ones) have next to no value at all.
You can purchase them buy the pound at flea markets or on the internet.
But to be safe - I'd take it to a local coin shop to make sure it's not valuable.
The good news is that any type of 1800's dated coin is a great find !
Looks like your coin could be from the Netherlands / Holland.
