There are absolutely cheap hat and cane chips out there. I found some plastic hot stamped chips on an
LCV mold mixed in with a hotstamp lot that were definitely not Paulsons, so they're out there. The mold work was very good, but the materials were clearly inferior. The vast majority of what I've seen and purchased from
eBay has been legitimate, though.
The only reason I mention
eBay and nothing else is that most chip purchases I'm aware of come from fellow chippers (generally safe), known retailers like Spinettis or Apache (generally safe), or
eBay (has the most risk of the three, IMO). It would very unusual for me to buy something off Craigslist or other sites without me knowing the seller or inspecting the merch first.
