If the design appeals to you because of the Egypt theme, there's a few other options you might consider to get a similar theme on a higher-quality chip:
Chipco Egyptians: these are casino-quality ceramics. Hard to find but sets are out there, and for the right price someone might be willing to part with their set. You'd have to post a wanted ad
and make some friendly contacts in the community and ask around
and do some research to see who might have some and reach out to them to see if they'd be willing to sell.

Pyramids Casino Spirit Molds: These are an older china clay chip. The base chips are called Spirit Molds; they were made with a couple of different stock labels, including this Pyramids Casino design. Spirit Molds have been out of print and out of stock for a while, but it's possible some people still have hoards of them, possibly still with the original Pyramids Casino label. Spirit Molds are an older china clay; they feel a lot more like "clay" and a lot less "plasticy" than newer chips such as the Milanos and Majestics you may have sampled, but they also sometimes are a lot more fragile and prone to chipping and breaking.

Apache Pharaoh's: These are a modern china clay chip. The design is a replica of the original Paulson Pharaoh's, which are clay. These are quite popular, well-regarded, readily available, and affordable.

And finally, you could go the custom route. If you're good with graphic design you could make your own set that's inspired by the Nile Clubs, or for a modest fee you could commission one of the many very talented graphic designers who hang out on PCF to produce something that incorporates whatever aspects of the Nile Clubs you find appealing. With that design in hand, you could get custom ceramics, or you could get custom labels made and relabel a china clay chip of your choice; this is a very common way for people to get nice-looking chips with a design that appeals to them on a decent-quality chip within a modest budget.
