Silver Dollar Identification

[Z Trip]

Hey every one. I always wanted silver dollars and so picked these ones up at my LFS. He told me their normal ones. Are they "normal" or are they a special type? Thanks

There are at least three "common" silver dollars, From the shape of the head and lack of spotting I would guess that those are Metynniss mola rather than the M. argenteus (rounder head), or the M. hypsauchen (usually faintly spotted). All are treated the same and get a max of 6".
