This series consists of the original unbound register slips (certificates) the State Treasurer's Office kept to show receipt for monies paid to the office by various people over time. The types of money paid to the Treasurer's Office are various: 1. taxes paid by the various county tax collectors for that year which sometimes included direct and general taxes, 2. installments paid on fractional surveys of land (which were not included in the general land lotteries but sold at public auction), 3. two folders containing receipts for funded certificates apparently used to pay for fractional surveys (all certificates seem to involve one of two men: Benjamin Andrew and James Spalding), 4. money paid for an auctioneer or peddler license, 5. Solicitor-General's payment on bonds delivered to him, 6. dividends payments to State by a bank the State had stock in, and 7. payment on an island in the Ocmulgee River.

The original slips have the "curvy" cuts on one side that were made at the time of payment. This was done so that the person receiving the receipt could prove at a later date that his receipt was authentic simply by fitting his receipt's "curvy" cut into the "curvy" cut of the slip still at the Treasurer's Office.

The register slips have original numbers on them although the number scheme sometimes doesn't make sense.
