Belgium Un Belga / 5 Francs Value

I can't seem to find a link anywhere for what the value on these coins is.  Anybody have any idea?  I know a lot of Nimistites have them, but I'm still curious...

EDIT:
Nevermind...didn't realize NGC had multiple variation on the 5 Franc denomination.  Though there does seem to be a discrepancy with the mintage numbers:
