Sirco had a business deal with a Lissepian freighter captain but was unable to pay for the ordered 100 gross of self-sealing stem bolts. Nog and Jake Sisko got the stem bolts in exchange for 5000 wrappages of yamok sauce.
Later the boys under the alias Noh-Jay Consortium contacted Sirco to sell him the stem-bolts in exchange for gold-pressed latinum. However, the Bajoran was unable to pay with latinum and proposed the deal, the stem bolts for seven tessipates of Bajoran land. The boys accepted this. (DS9: "Progress")
