An inconspicuous banknote, but in terms of rarity of variety it is one of the rarest Polish banknotes of the 20th century.
The "jenerał..." issue was characterized by a 6-digit numerator. All 100-mark banknotes from the General issue have a 7-digit numerator. The final, presumably very small batch of 100 mkp jenerał banknotes was also numbered with 7-digit numbering - just like the "Generals." The 7-digit "jenerals" are among the greatest rarities. They are virtually unheard of on the market, sought after and valued even in poor states of preservation.
