1. Looks like 1879, can't see any mint Mark below wreath.
2. So the 1878 rev has no standing here.
3. You can call it XF based on wear. Photograde.com is a good site for nailing down condition.
4. Color actually not very relevant to this grade, toning is a distinct characteristic from level of wear. Just tells us this is original, don't clear it!
5. Value $28.
