1957 2-Deutch Mark. Grade And Value?

I can't quite make out the mintmark, but it looks like a "J" to me. There were four mintmarks issued for this coin in 1957; D, F, G and J. The commonest is J ($60 in Unc) with D and F not far behind ($65 in Unc). G is much pricier ($135 in Unc). I'm using a slightly older Krause (2006) for the prices here.

The mintmark is the tiny letter, just above the tail-end of the "2". You've got the coin in hand; can you confirm the mintmark?

I also note a major disparity in Krause between EF and Unc prices. The prices in EF come down to $6, $6 and $7.50 respectively. So it appears to matter a great deal whether it's genuinely uncirculated or not. It's really too hard to be sure from those photos, so I'd have to err on the side of caution and say it's at least AU. No idea what to do with an AU price, based on Krause; suggest halfway between the EF and Unc prices as a ballpark ($33, $35 and $70 respectively).
