I saw this on eBay and this is what they said:

This is a Limoges hand-painted tea cup with saucer. The cup has a British Tax Stamp dating the cup to pre-revolutionary war times. The tea cup has beautiful hand-painted gold accents and well as an intricate shaped handle. The cup and saucer is not a perfect match and the saucer does NOT have a Tax Stamp. The gold striping on the inside of the lip is worn some and there are some worn spots on the handle as well. Now is your chance to own this tea cup that dates pre-1770's. Own a piece of this country's history!
