I have an old table and it has the numbers 854740 on it is it antique

You need to know who made it. If you can't find that, then take plenty of pictures (or take the table itself) to a local antique dealer. They, typically, can tell a lot about it from it's style.

I've had no luck finding anything about it based on that number, so I'm thinking that a local antique furniture dealer will be your best bet.

Hi, twochildren02!

Would you be able to post an image or two of it here, please?

Thanks!
