Victorian buttons, Edwardian buttons and others
Items, things, artifacts, relics over 100 years old are called antiques. Everything less than 100 years is Vintage. A few of the buttons were made with au gold. But more important are the levels of details. The time it took to cut all the fine details into a die is quite remarkable considering the day and age it was done in, the 19th century, mid to late 1800's and early 1900's for the Edwardian era..... this is just one reason why people collect sewing buttons. Another is, just how many have survived. You can inquire about them at; firstname.lastname@example.org
