Antique covered casserole dish

There's not enough crazing for me to suggest it as being 1800s, but it does somewhat look like an older piece.  Items that are not marked are difficult to appraise or give details about, most of the time that is. Usually unmarked items are worth very little unless they can be proven to be of a brand that just did not mark their items at that time period. It appears Asian in origin, probably Chinese. So much came out of China unmarked then and now, that it's hard to find details on anything unmarked and Chinese. If only it were marked. If you can, take some clear close ups of it, and of the bottom. I might be able to give more insight if I can see the condition and bottom better.

It looks like a reproduction to me , it's too glossy to be an original. Many of these were made during the 1980's when values for Victorian examples were amping up.
