These are Victorian or Edwardian sterling silver brooches. They are called posey holders or "tussie-mussies." These types of brooches were used to hold real flowers and worn as a brooch. Only one of the two brooches is marked STERLING (both test sterling). There is an incomplete designer's name on that brooch as well. Each brooch has an applied leaf on the front. The brooches measure approximately 1 7/8 inches wide by 7/8 inches tall. The two weigh 12 grams. The brooches are in good condition; they do have a patina that I did not clean the silver is easily polished.
The term tussie-mussie comes from the reign of Queen Victoria (1837–1901) when small bouquets were a fashion accessory. Typically, tussie-mussies included flowers that were symbolic and intended to send a message to the recipient. In more modern times, the term specifically refers to a small bouquet in a conical metal holder. It can also refer to the holder itself, particularly when used in a formal wedding. Because the brooches match, these two tussie-mussies are likely left from such a wedding
