Hi Peter.....why ask one of most experienced group of meteorite
enthusiasts and experts (all of which are passionate about helping
others to search for new finds and material) for an opinion based on a
visual analysis/photos of your samples if you are certain for yourself
and are willing to dismiss a unanimous verdict....if you are that
certain they are meteorites then you should submit samples to an
experienced university for scientific analysis. Even if we had all
agreed that they were meteorites that would still be the
recommendation.

Good luck.

Graham
