Well, I guess that's your decision to make. They're great
looking chips that don't quite stack as well as what we think Paulsons should stack like. This is probably due to a slight imperfection in the new mold (with suits, etc.) and/or a change in materials for home-quality Paulsons.
In that first link I posted, a "newb" made a very nice summary of the discussion... in case you didn't get that far, here's a link directly to that post:

Apache's a great vendor and I'm glad to hear they'll let you return your chips if you want. It's totally up to you. You shouldn't be unsatisfied with a $1k purchase. But at the same time, if you go to the M2M and Want-to-Trade forums here, you'll find that there's still a 2nd hand market for them, just as there would be for any new chip. Some people don't mind the slight imperfections, while it bothers others (just like mis-shapen inlays of older BCCs bothered a lot of people).
