It looks still better than my 63 CC Morgan, esp. the reverse is very nice and clean, it could go 64...
Agree that much of what's going on are luster grazes and I've seen that many on Gem BU grades. Here's one of mine with a lot of luster grazes, not contact marks:
63+ wouldn't be surprised if a tpg went 64 tho. Nice frosty one reminds me of an Ice cold mug of beer
Comparing a DPL/DMPL Morgan to a non-prooflike Morgan is folly. DMPL's are graded with far more leniency due to the generally heavily frosted devices and reflective fields. I would call the OP's coin a 63 with a good shot at a plus.
