Boston Terrier Paperweight

My parents just bought this little guy for my birthday. I was super excited as I've been searching for one. I originally wanted a large one but this little guy is too cute. I absolutely love the patina on him. I am curious as to his history and if he could be a hubley or possibly a reproduction. You can see between his ears is a area of metal that I've never seen before. Can anyone give me some information on the origination of this little guy? Thanks!!!
