hello,
The Zodiac Lion was introduced by the decree of 16th July 1984. Here is my source.

It was cancelled by the decree of 1st August 2000, however it hadn't actually been used since 1994. Quite a few hallmarks that hadn't been used since 1994 were only suppressed in 2000 to tidy things up a bit. Here is my source.

So the zodiacal lion was only used for ten years in fact. I would be surprised to see it on an antique object. Other more recent hallmarks can indeed be found on much older objects, but the lion was only applied when taxes were refunded, and I can't see any way they could be refunded on old objects, the taxes are only refunded to the silversmith who manufactured the object and paid the taxes on it initially.
Here's what I have in my book :
244. Zodiac sign of Leo in a round frame. Introduced by decree no. 84-624 of
16 July 1984, it was stamped on French-made gold or silver works bearing regulatory
domestic hallmarks and awaiting export with the request for reimbursement of excise
rights. This mark was inscribed next to the excise mark. Works bearing this mark are
not valid on French territory. The Director of the hallmark office could, at the request
of the exporter, grant him the right to store the punch and to stamp the mark himself(108).
Paris and departments, from 16 July 1984 to 1 August 2000 (withdrawn according to
decree no. 2000-745), but in fact it does not appear to have been employed since 1994 [97]
By the way, I made an interesting discovery two weeks ago. The mark MD, for Métaux Divers, which is usually found on gold or silver items with steel springs or pins, was also used on gold items with platinum between 1896 and 1910. It was only in 1910 that platinum started being treated and taxed as a precious metal in France, and until then it was considered a Diverse Metal !
