I goofed. There are actually four cited in Rostovtsev. I should dig up the other two citations and see if I have a good pedigree here.
Question: If you were one who attended a ceremony dedicating the lighthouse what part did tessara such as this play either before or after the event? Was it an entrance ticket or a take home memento of the day? Did it have a cash value or could be traded in for measure of grain? Did people save/collect such things or show them to their patrons as evidence of participation? In some periods it seems that the mint issued special coins (often asses) for distribution to the crowd but these would have been spendable cash. What, why, who tessara? For something made simply and easily in large or small numbers, we might ask if they were always rare or simple swept out with the refuse explaining why few survive.
These are all excellent questions. According to my model, most tesserae, this included, would have circulated as small-denomination coinage. I have no good archaeological evidence for tokens from the city of Rome, but leads from other areas exhibited a find spot pattern more suggestive of coinage than of tickets. Your suggestion that these could be kept as a keep sake is interesting. They undoubtedly had a small value in trade, and if a middle-class citizen caught one, they may have been more inclined to hang on to it than drop it in the till. Who made them? I have no idea. The technical skill demonstrated in the engraving and production is vastly inferior to that of the official mint. This is undoubtedly an intentional move on behalf of the anonymous issuer to reduce production costs. I envision a number of private manufacturers of tesserae, selling tokens to both the government and private individuals, with shopkeepers ordering them to use as change, and patrons ordering them to give to their clients.
This one is a coin that I won in a contest from @lordmarcovan: an Antoninus Pius provincial of Antioch on Orontes

I bought this as when I was a teen visiting Tunisia... It was in Thuburbo Majus. Patinated, corroded, high relief : it was for me, at this time, the very symbol of what an ancient coin was. Another sestertius of Antoninus Pius (this one posthumous) :

Here are my two examples. First the denarius. Denarius of Antonius Pius, Obverse: ANTONINVS AVG PIVS A P TR P XI “Antoninus, augustus, dutiful, patriotic (Pius Felix) --- Tribune of Rome 11th year.” Reverse: COS IIII, “Consul fourth year.” Denarius of Antoninus Pius, laureate head, Fortuna standing, holding a rudder and globe in her right hand cradling a cornucopia in her left hand. Sear - 4073, Year TR P XI - 148 And then my one and only aureus. I understand that Antoninus Pius is the most common aureus. I really wanted to get at least one. Aureus of Antonius Pius, Obverse: ANTONINVS AVG PIVS P P IMP II “Antoninus augustus pius father of his country (Pater Patriae) Emperor. Reverse: TR POT XX COS IIII “Tribune Potestas 20 Consul 4 (year 156-7 AD) Victory advancing holding a wreath and palm. Sear 4028
