Sorry, but no, your button showing the emblem of the Royal Black Heath Golf Club (in Scotland) is not an antique/historical button. It is a very common "Fashion" button made is several variations for use on Sports jackets, particularly, of course, golfing jackets. If I recall correctly, it is still being made and sold today by the Waterbury Button Company, available at that company's website in the Fashion buttons section. Many of RBHGC variations have showed up here in the What Is It? forum. My computer died, so I can't post photos for you which show the several variations. Somebody else has probably also saved those photos, and can post them.
Your button's "square self-shank" on an iron back dates it to being manufactured in the mid-1900s to the present.
