I collect crest and seals and ivory. I have no limit in these two areas. If it's a c&s or ivory and I need it, I'll try and get it.

Just because, in general, there are no denominations (in c&s anyway), it doesn't mean they are cheap. I've paid upwards of $2K for a C&S.

Now, unlike casino chips, new c&s are not issued every day. Those that are issued (by pokerchipsonline.com) are chaep.
