Hi Folks,
I have a few newbie questions related to notched chips. Typically notched chips fall under the cancelled category, which makes sense becase that's what they are. But I recently read somewhere that some manufacture's kept notched samples for their records of all the chips they produced. Also, notched samples were sent to casinos as well.

Regarding older Nevada chips, did any casino's cancel their chips in mass this way or is the more frequent practice just to drill or overstamp them?

I haven't been collecting very long, but I really don't see a lot of notched chips for sale (see more drilled chips). Now I know there are rare proto-type chips that are one-of-a-kinds, but are regular issuse notched chips more scarce than un-notched? For example, if I know there is a box of the Sands $25 chips out there somewhere, is it possible that there are only a few of these around as notched samples? And if they are really samples, I would think they would be in great condition.

I don't specifically collect notched chips, I just picked these up because they were pretty cheap, great condition and I like the way they look. The notches don't really bother me. Does anyone have specific information to the below chips? Thanks for any help and/or comments!
