Jaelus' Hungarian Mint Errors

Set Description
This is a set of Hungarian circulating issue mint errors to accompany the coins in my main Hungarian sets (1848-Present).

Set Goals
I am attempting to collect major errors of Hungarian circulating issues as I see attractive and interesting examples come to market. I am particularly interested in mint errors from the Austro-Hungarian compromise period (1868-1918), though they are very difficult to find.

Of particular interest to me in modern errors are the hole error types of the 2 fillér KM-546 (1950-1989) and KM-673 (1990-1992). Currently I have examples of KM-546 with a major offset hole and with double punched holes, however, I am still looking for an example with the hole absent entirely, as well as comparable examples of these error types in the short-lived KM-673.
