Just about the most common question anyone asks button collectors. We all have a sense of style, pick out the ones you think are nicest and list them in a group. Don't make claims you cannot back up "for sure" such as "rare", "scarce" or name materials you are not certain of. Show fronts and backs of the buttons and not so far away that people can't see what you're offering, show well lit, close-up images. Best of luck !
