20 Mark Hessen Germany 1911

Thank you for the answer! You are right about the weak strike. I am also in a german numismatic platform and there is only one collector who owns a coin from 1911 with full details. I also own an Ernst Ludwig that is (maybe wrong) in an NGC MS 61 slab, but this one here has a better luster (especially in the hair and at the cheekbone). People only paid for 3 years with this type of coin (1911 to 1914)but it is almost impossible to find an attractive example.
NGC gradet 4 as AU 58, 7 as MS 61, 4 as MS 62 and 2 as MS 63 and 1 as MS 64 (I saw this coin at HA and it is very scretchy )
PCGS gradet 5 as AU 58, 4 as MS 61, 1 as MS 62 and 2 as MS 63

Are there further opinions?

Do you speak of the first or of the secound coin? I find the free one is better than the one in slab (which was gradet ms 61 although it has a loss of detail by harm). The 2nd one has much more mint luster (even at the hair) and better fields. On the other hand it has scratches, what is normal for this type. German mint law allowed the delivery in rolls and in bags. It seams that Hessen always ordered in bags from the mint in Berlin which made the typical goldcoin with Wilhelm II as well.
