Dating Vintage Dinnerware By Words Found In Marks

Dating Dinnerware

So let’s say you feel like spending the day browsing the local thrift store’s selection of vintage (or not so vintage) dinnerware. How are you going to know if that beautiful piece you’re holding is an antique or just some mid-90s knock-off?


One way to tell is by reading words that are included in marks. Certain words or phrases were printed next to the mark, either because of a new feature or a new law.

If you know when these phrases were introduced, then you at least know the maximum age of a certain piece of dinnerware.

The list below should help you on your journey to figuring out how old your vintage dinnerware actually is. Good luck!
