Starting from smaller one on left you have 3 clays, Peltier Rainbo, maybe a Slag, another clay, Bennington, patch?, Bennington, MK, ?, ?, Bennington at the top.
Here is a pic of my Confetti bag. Also, here is Pete's decription from his Mega spreadsheet - Single-color, 6 vane cat's-eyes in assorted colors. Iridescent finish.
Packaging has more value than the marbles. I did not see any valuable marbles in the packages. The bumblebees in the first are the only "named" ones. I wish Gerald Witcher could get his book published. He has a ton of information on the dates, headers, etc. from MK as well as the marbles, history and more. The Gladding-Vitro bag is between 1969 and 1982 when Gladding owned Vitro. Others are generally from the 60's, maybe late 50's on the Rainbows.
The marble shown is a common foreign - usually Japanese or other Far East - 6 vane cat's-eye. This one is a white cross-thru as only the white vanes are across from each other. The other vanes for the color "v" on each side.
Left - contemporary; right - ? If the contemporary has name or initials, may have a little value depending on the maker but looks pretty simple so the few buck range at most.
