Hi. You will not find any modern copies of antique weights that are good enough to fool anyone - there are some dire attempts from China, but they are awfully crude. There are weights made by modern makers in the antique style, but they are proud of them, and sign them - and they do not attempt to replicate the exact detail of the millefiori, which would be very difficult. I am sure your weight is 100% antique, and is a Clichy. I think the condition probably indicates that it has been re-polished. I cannot see from the images whether there is a wear rim on the base - if not, it has been repolished. If the wear rim is somewhat uneven in width it may indicate that it has been repolished, too.
