I have included some photos of an old prototype now. The design has changed entirely since this one but at least you will have a better idea of how the set works.
That's actually a rather clever design. Some tips I would offer:
Make the cards out of plastic. For a deck like this, durability has to trump handling. And make certain that the back has a true, one-way design. A real card player wouldn't play a money game with a deck having a one-way back like this one does. When held vertically, all the card backs should be completely the same in appearance when turned 180 degrees. You must have tested this prototype - can it be riffle-shuffled? If not, it needs some kind of improvement.
Make the chips out of plastic - but not "chip plastic." Use the same plastic that's used for the plastic cards and you'll have a stack of chips equal in size to the deck thickness (and almost no wasted plastic). Paper
anything in this deck is too flimsy. Consider even getting some sort of heavy-duty plastic box. You could promote the entire set as being waterproof, making it ideal for travel under most circumstances. You can also promote it as a "must-have" for anyone's disaster-preparedness kit or "go" bag - a waterproof poker set that takes up the space of a single deck. Heck, you might even find "prepper" (formerly known as "survivalist") supply retailers interested in carrying your decks, either individually or as part of one of the aforementioned disaster kits.
Consider making the chip tubes screw-down or pop-top - it will hold up better and is less flimsy. Mark the ends of the tubes - one can be your "dealer" marker, the other you can mark "blind", and if you wish to take it further, mark the cap of the "blind" tube "little blind," so it can be a separate marker for games with two blinds. Make all the markers different colors to easily distinguish them from each other. Using halves as chip holders is less practical - when holding chips the base surface is curved and unstable, and if one player wins more than half of the chips, he'll need another chip holder. Just let them leave their chips on their playing surface. The most commonly-played poker game for the past several years is Texas Hold 'Em and it requires playing on some sort of table. You could use a deck box that separates to two large, flat halves - one "tray" holds the pot, the other holds the bank.
The chips - leave off any value markers. The most common practice for a set of this size would be to make 50% of the chips one color (usually white) with the remaining 50% split evenly between two other colors (usually red and blue). You can, and should, make a decorative edge pattern, but leave the values up to whatever the players themselves want. If it's possible, after the chips have been punched out of the card plastic, get the cut edges colored to match the chip colors, perhaps with white, yellow or black stripes to break up the color pattern in a similar fashion to casino-grade chips. It makes the chips easier to identify and count in a stack.
That's all I can come up with in a nutshell.
