"God only knows what might be in the missing 113 plays!"
Probably the BEST of the plays by these authors were the ones that were copied over and over (and over and over. . .), so that the rest are probably of lesser value.
BUT, that said, this may be the best deal since we started looked at mumified Ibis birds in Egypt. (The wrappings were made in late antiquity of shreds of books, among other things. From there we have some Greek plays, the earliest scrap of the gospel of John, and much else.)
How about finding a copy of Claudius' History of Carthage? Or a history of the Etruscans? (Much of what we "know" is only guesswork)
Or. . . ?
On the other hand, Aeschylus won the first prize at the Greater Dionysia thirteen times, but we only have seven of his plays surviving. In any case, even finding a cartload of rubbishy Plautus knock-offs would at least improve our understanding of Roman society and the Latin language.

My personal prize would be Cato's legendary History of Rome. He is said to have been disgusted by the hero-worship which had arisen in his own times, and so in his History he referred to nobody at all by name. The only exception was Hannibal's elephant, Surus, whom Cato conceded had done more than could be reasonably expected of any elephant.
