What Stone Agates Are Considered Rare?

[MarbleDawg86]

I recently came across a 2"+ flint hand faceted marble at a yard sale. It was marked $3.00, so i purchased it... I was just wondering if this is an unusual size or marble for that matter? What non-glass marbles are considered rare?

I don't think it would have been a playing marble at that size. More along the lines of a "mineral sphere." Or a target. Not that I'd shoot any of MY marbles at it, even if mine were flint too. And there are a few people who still make their own flinties for use in Rolley Hole and other old-school marble games.

Whatever it is, I think $3 sounds like a very good deal, whether new or old. But that may just be me.
