For true coins you're fairly limited. I really like Stokkebye's Luxury Bullseye Flake but in my opinion it needs at least six months of age on it before it really shines. The longer the better. Davidoff's Flake Medallions gets a good rap although I've never tried it. Peterson/Dunhill De Luxe Navy Rolls are, at least to my palatte, very similar to Escudo at a higher price.
If you're comfortable getting a bit weird and a lot Danish then MacBaren's slew of lumpy coins can be very good. Doblone D'Oro and Dark Twist being the always available standouts.
Gawith's various ropes are also ripe for being cut into coins and a far departure from Escudo.
As for Navy Flake, it's kind of like "English Blend" where it's usually a catch all term for virginia flakes usually with some kind of alcohol topping to various strengths. Again Stokkebye reigns supreme. Both Luxury Navy Flake and Luxury Twist Flake are very good, especially with age. MacBaren/Newminster's No. 400 Superior Navy Flake is also great, at an even better price, but it's stretching the definition of Navy Flake. Dan Tobacco's Salty Dogs is a really fantastic VaPer, kind of Navy Plug I guess. GL Pease's Windjammer is fantastic with a lot going on.
