Austria. Karl I. 20 Heller 1918 (No reserve price)

The 20 Heller coin dated 1918 features Karl I, the last Emperor of Austria and King of Hungary. His brief reign from 1916 to 1918 coincided with the final tumultuous years of World War I and the eventual dissolution of the Austro-Hungarian Empire. Coins minted during his reign are historically significant as they represent the end of an imperial era in Central Europe. The 20 Heller was a minor currency denomination used for daily transactions, and coins from this period often are sought after by collectors for their association with the dramatic political shifts that led to the formation of new nation-states in the post-war period.
