I examined these with my stereomicroscope at about 60x and there was no visible crater effect. I know this can happen because I found many of them in the same Mint bag that appeared on the brim of John Muir&#039;s hat and culminated in a full-blown die break at the same spot. There were also a few sunken marks on the right side of El Capitan. Unfortunately, I never found a full-blown die break for any of those.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
