Nooo, don't chuck it in the tip, it's sounds like a lovely set and probably worth taking to the nearest Auction house, for them to sell.
Yes, you may see hundreds / thousands of similar items, items do slip the net and become listed as there are over 7 bllion listings on at any one time so impossible to check each and every one. Also, laws can be different if being shipped from a different country.
Those that have broken those rules, when they are spotted and reported like yours was, they too will be removed.
Your item has been flagged up, spotted and reported so it cannot be relisted on eBay, but do try and sell it elsewhere, if an antique, then it's too good to just tip.
