Victorian buttons, Edwardian buttons and others
Items, artifacts, relics, anything over 100 years old, as I have been told and through a little research, are referred to as antiques. Everything less than 100 years is Vintage and I think a car over 25 years is called a classic......thought I throw that in there. :) A few of the buttons may be plated with au gold but I don't guarantee this. More info on gilded buttons can be found here. But more importantly are the levels of details. The time and effort they took to cut all those fine details into a die is quite remarkable considering the day and age it was done in, mid to late 1800's and early 1900's for the Edwardian era..... This is just one of many reasons why buttons art collectible. Another is, just how many have survived. And the lessons of life, reminders of good and evil that were depicted in the images. I saw these at an auction and instantly fell in love with them. You can inquire about this collection at; email@example.com but be warned, I'm not an expert in this area. $2500 for all 61 buttons. A few duplicates but in smaller diameter size.
