For the record, I think it wise to suggest to
readers that not all "sand dune" stamps are worthless,
experienced collectors can spot them, but for possible newbies,
early trucial States or "Dune stamps" can fetch over $100
"early" (pre 1966) and "on cover" are the things to watch.
I post a snippet from the Australian Stamp News
author Rod Peryy's woodchip free zone
discussing "contrarism" ie going against current collecting trends
