Welcome to the board. The majority of marbles you are showing look newer and/or foreign-made, although a few may have been made in the USA. At a glance, I do not see any that look particularly special. You may want to take group shots of about 20-40 marbles, in a single layer, and as close as you can get, and post them in the ID section. That way, it will be easier see what all you have and we can identify any that might require a closer look.
Regards,
