I would greatly appreciate your thoughts on this goblet. It stands four inches tall, is decorated with a frieze of birds and dwellings and has to marks to the base. The first appears to be a numerical number five and a small dot or character; the second a fleur de lis. We wondered if if it may be Czech because of the number five (denoting 800 silver?) but it doesn't match the other images here on 925-1000. Thanks.
