They are mostly c 1920 - 1935s machine made in USA.
Picture one shows a variety of USA made 'Agate / Slag' marbles - the swirled colour marbles look like 'Christensen', 'Peltier', 'Akro' but could also be by a raft of other USA companies - this is the best link you will find http://www.marblealan.com/
(see 'Identification guide'
The two toned marbles (without clear glass) are very interesting and look like 'Akro Prize Name' marbles.
Picture two 'Agate / Slag' marbles 'Christensen', 'Peltier', 'Akro', etc. (again have a look at site) 'Whirpool Swirls' & 'Two Tone Swirs' perhaps- I don't know what the large striped sphere is (looks interesting) right under it looks like an 'Akro Rainbow'
Very front looks like a 'Core Onionskin' not to sure - is USA 1920s and not a 'Cats Eye'
Most interesting for me is the opaque marble with the clear and coloured 'Eye' sections - I don't know what it is - I am sure the guy that runs the above site will.
It is pretty complex as you will see - so I may be well off
You could do worse than send a good selection of JPEGS to guys email at bottom of main page - he has helped me in the past.
