BULGARIA. 20 Leva, 1894-KB. Kremnica Mint. Ferdinand I. NGC AU-55. Fr-3; KM-20. An elusive and always popular type, particularly when preserved as nicely as this specimen, this nearly uncirculated 20 Leva delivers good retained details, with a bright luster throughout. Limitedly handled and nearly as attractive when it was issued, this 20 Leva is certain to fill a hole in the next collection it enters.
