I would send it to NGC or PCGS
for a crossover. Don't worry about whether their grade may be lower. The respectability of the grading will add value.
Crack it out first (carefully!), then submit to your preferred TPG
per the appropriate guidelines.
It's a great looking coin, but I can't venture a grade with the pics provided, mainly for being too dark.
