Mo. Rev. Stat. § 33.540

All bonds purchased or paid under the laws of this state shall be deposited with the state treasurer, who shall immediately proceed, in the presence of the fund commissioners, to cancel the bonds and all attached coupons by punching in a manner to preclude the possibility of negotiation, use or sale. He shall register the cancelled bonds in a well-bound book kept for that purpose, designated "the redeemed bond register". The bonds shall be registered by their numbers, dates, series and amounts, the date of their payment or purchase, to whom paid or from whom purchased, and under what law it was done.
