OK, check out chiptalk.net.
All the chips you posted are what's known as slugged ABS (plastic) chips. They're all basically the same, a plastic coating over a metal slug for weight. They vary in actual cost but are generally the cheapest. Generally this is what a lot of people end up with because they are available everywhere and they are relatively inexpensive. They do have some downside because they don't stack very well (they're slippery) and they have a distinct metal clack when shuffled / splashed. The color on these chip is molded throughout the plastic. Outside of a few high end ($1+/chip) ABS chips these are generally not use in casinos
Another type of chip are what's known as ceramic (even though they are made from injection molded plastic). These chips (like mine above) do not have a metal insert and generally weigh in at about 10g (what most casino chips actually weigh contrary to the ad hype on most "official weight 11g chips"). They can be printed from edge to edge (and even printed on the rolling edge) and can generally have any type of art you want. They do not have the metal sound of ABS chips but don't have the same dull thud of clay chips (it's kind of in between). Some high end ceramics ($1+/chip), mainly Chipcos, are used in casinos.
Clay chips are the 3rd basic type, even though once again they are now made from plastic (again different from that used in either of the above types). They are not printed on directly and feature a permenant label applied to each chips center. True clay chips are always expensive ($1+/chip) and are generally the chips used in casinos. Paulsson chips are the industry standard for clays but complanies like Blue Chip and ASM offer the home game player willing to spend the cash on clays the best bang for the buck.
If you really prefer the hotstamp look generally that is only available on some ABS chips and most clay chips.
As for my chips they were printed by Sunfly on Sunfly blanks and ordered through Palm Imports.
If you PM me your mailing address I will send you out a sample set of my chips to see how you like them compared to the samples you already have.
