The Cadino Da Vinci chips are far superior to the Milano chips. They were one of the very first china clay chip designs (made by Eastony Industries for DaVinci Imports) using the spirit mold, and are much closer in sound and feel to real clay chips than the more modern plasticized china clays sold today.
Although no longer produced, the older spirit mold china chips were widely sold with other themed artwork (Pryamid Casino, etc.) and also as blanks (no labels) with a variety of different edge spots and colors (mostly 4d14 pattern), meaning that there are a large number of them in existence -- which you might pry out of hiding in the used chip market, typically at 20c-25c or less.
There may be other scattered stashes of new old stock (mostly blanks) still out there on various old web sites that could be garnered at a discount, but will require some dedicated searching.
Afaik, there aren't any older-style china clay chips that offered nickel denominations except for the Pharaoh's Club & Casino, which although on a different mold, can be reasonbly paired with the spirit mold chips.
There were also a large number of similar-material china clays made using other molds (Dunes, Desert Palms, greek key, among others) that used either similar spot patterns or 8V spots, that would work as part of an older
cc set.
They all turn up in the PCF classifieds and other places (
eBay, craigslist, facebook, etc.), but if you're looking for a single turnkey solution meeting all of your requirements and within your budget constraints, it's simply not gonna happen. It will take time, patience, and money.
