Hi Eric, thanks for your feedback. The reason that all these chips are rare for collectors and are hard to acquire is because none of them are freely available for customers to purchase. Most of them are strictly for internal use only. I hope this answers your question

PS - these 10 chips are not the only hard to get chips from my last holiday, they are just the hard to get chips that I was able to get that weren’t on the Chip Guide. I probably didn’t make that clear in my initial post.

Kind regards
David Moors
