I got this Tropicana chip recently and need to know which TCR entry it matches. The main entry is TCR N6577, but there are two entries for NCV's of this style. One mentions just No Cash Value, while the other describes the TR King name and the "souvenir" stamp. Has anyone seen the other type NCV chip? One is suffix "C" and the other "C2". I'm assuming mine is N6577.C2 but am curious as to what the other looks like.
