Louis, They should play at around 78...Library of Congress uses Simon Yorke Decks that go from 0 rpm to about 100 rpm. There are some more affordable decks out there that play at 78...... and of course the classics like Garrard 301 and 401 and Thorens TD124...and cartridges for mono and styluses for 78s! Good luck!
The original jazz stars as far as the wider world knew. Actually, not bad. I actually inherited three or four of their original (shellac?) records which I have stashed away. I think I would need a record player capable of playing at something like 16 revs per minute to get sound out of them. Nice to have links back to the birth of recorded jazz.
