These are real beauties.  It's rare to find this many matching Waistcoat Buttons at once.  The lighting does not do them justice.  They are dark green and have specks of aventurine .  They can be seen in the Big Book of Buttons in plate 59 #70. The value listed is $5-10 each.  The 22 piece set has 3 red spots on each button.  There are 8 that have a swirly yellow with brown spots.  The set with 15 are plain green.  They are just shy of half inch at 4/10".  I don't believe they have ever been used.
