as an item of pressed glass, this one joins the millions of other pieces made by a basically similar process, the overall total of which probably far exceeds glass made by all other processes put together, so unless the pattern of your piece is recognized - by means of linking to an old pattern/design - then you will probably not succeed with an id.
This probably sounds depressing, and not what someone wants to hear, but it's an unfortunate fact of life. Some countries do keep extensive industrial manufacturing archives, and depending on the extent of research you may, or may not wish to undertake, then it's possible to locate some really quite old pressed glass designs, and as a by product all the history that goes with it. Of course not everyone wants to delve that deep into what in reality is a piece of cheap utility glass that lacks intrinsic or historic value, but as Anne has said, if you like it then keep it - who knows, it might be the beginning of a long interest in the history of pressed glass, which I can recommend by the way.

Unfortunately, the GMB presently lacks regular support from pressed glass collectors on your side, and folk here concentrate on European material. If you can locate pressed glass forums in the Sates then they may provide you with shorter odds for getting an id for your plate - wish you luck
