I bought a sliver platter that is really pretty has a real fancy designs on it and on the back it says "500,000 club 1960" what does that mean and is it a antique

Hi, samantha22!

I'm going to do some researching about this. In the meantime, would it be possible for you to post an image of it here so that we know more about what this is? Also, would you provide the dimensions of it, please?

Thanks!
