First one is a chalice, second one is a little more difficult, could be a chalice, a favia, an acan echinata, it’s hard to tell without a size reference and a better pic. Regardless, $10 for a colorful frag of any of those is a good deal. Does the person selling them not know what they are?
Through someone locally, they just don't know the names of everything, there were about 30 LPS and a few softies so. Man was also kinda bowed up. Also got a leather, and 2 torches for $60 all together, but yeah. I COULDN'T beat the deal. However was curious. I knew about the chalice, well was confident. Just not so much the other.
