The Nova Group was a group of eight different marbles that were made in 1988 by Peltier.
Please see the photo below
The first two have different characteristics (Narrow bands and a Swiggle) that don't allow them to be Novas.
The only Official Names are
Nova (3rd over at the top.)
Root Beer Float (2nd over at the bottom)
Pink Champagne (Last on the bottom).
None of the others were given names.
