The investment fund's vouchers were issued in ten series, marked with Roman numerals from I to X. Each series included 40,000 vouchers.
The vouchers were perpetual, interest-free debentures of the Treasury. They were accepted at face value by the coffers of tax and customs offices for payment of all state taxes and tributes, fines and fees, and customs duties.
Redemption of the vouchers took place through weekly draws. These were bonus vouchers - as the drawn pieces were redeemed by the state for 100 zlotys for each 25-zloty voucher.
Vouchers with numbering other than five-digit are encountered extremely rarely - single pieces with four-digit numbering are known (such as the piece shown in J. Moczydłowski's catalog). Surviving pieces with three-digit numbering known only from Series II.
A great rarity!
