Vacor. There are vintage machine mades very near this, made by Alley and Champion. Once you have some in hand side by side, you can see the difference in the blues and whites.
Vitro All Red. Named by the company. A white base with one red patch and a patch of another color. All Red because when the kids shoot or roll the marble, the red flashes or always seen and red was the kids favorite color on a marble.
Don't be shocked when someone tells you it is CAC. Years ago these were all CAC. Then good numbers were being dug at Pennsboro and then they were found in two of Alleys grandsons collections. Most people switched them from CAC to Alley.
All depends on condition and size of each one. The large one looks like it might be a yellow latticino. Cannot tell much about the yellow one. I don't think any are onionskins. With only this one picture maybe $150.00 to $250.00 . With just this one picture only the price estimate could be off. Better closer individual pictures with sizes might get a more accurate value.
Not Oxblood. Not black just thick dark red. Looks like it was dug, small lines, grooves, of abalone(silver looking). A reaction with some glass after being buried in the ground for a long time. Not all dug marbles do this or have this.
The second one (orange) is Champion Agate. The others are common game marbles. Made by almost very marble company from 1930;s until recently. Very few can be separated to one company or a certain time frame. They were made in many different single colors. Sizes 1/2 inch, 9/16, 5/8 are the most common sizes. Some are 3/4 and 7/8 inch.
Left to right. I assume they are all 5/8 size ??
