Hi Serine.  Welcome.
 
	 
 
	I think mostly a fun collection.  
	Mixed ages.    
	Some from around 1930 and a smattering of others right up to modern day.  Also a mix of makers.  Peltier, Vitro, Master, Peltier, some from Asia (we wouldn't be able to tell company names for those), and I think some from West Virginia swirl companiees.
 
	 
 
	In your last photo, there is a black and red one which might be the most valuable in the lot -- assuming it is mint condition -- which I'll guess it isn't.  A single chip can knock marble value down by half or more.
 
	One very interesting one to me is the swirly one with the inky blue ribbon on a white and clear base, with a touch of yellow.
 
	 
 
	Nothing is standing out as very valuable, but I'd pull out the two I mentioned.
