Cancelling this sale. Apparently no interest even at super low prices.
I've found a way to make use of these chips through relabeling, without going against my principle of not mixing "original" CPCs with "fixed" chips in a set. They'll become no-denoms with an easily distinguishable version of the Club Hel logo to form a separate mini set.
It won't be remotely as nice and easy as with my actual chip sets, but I calculated that the counts will just so work for five players, with a smallish but sufficient bank. Removing the denominations makes it possible to also play lower stakes than 25c/50c or 25c/25c.
Going to store them at the office... you never know.
