I am a reader of this site for some time without being registered. I just had some parts cheaper than the professional sellers offer them and wanted to share it (my ads are also on ebay) I'm from France, 33yo and foremost collector! Good day to all, even the trolls
The market is very small, there is a little bullion's collector . The French people prefer the old gold coins (Napoleon) but since some years sellers begin to sell silver Oz. Monnaie de Paris ( French Mint) make some coins but they are ugly ( Personal opinion!) A french guy who has a good page in France (I find). http://monnaies-commemoratives-modernes.over-blog.com/
No Tax for buying gold , you can find at spot. Silver you have tax 19.6% . Tax for selling 8% (Tax on raw material)or Tax on increase in value (35%) or after 12years no tax.
