There sure is....check "tintype" in ebay....and even Daguerrotype.
Keep in mind that everything listed as "tintype photo" isn't a tintype.

Most old photos are worth very little. However, civil war related photos are very collectable. Esp. cart de visit (probably misspelled) I once sold an album of them for $1000.00 I've also sold old photos of downtown areas of large cities for some good money. For example a large cabinet photo of downtown Bath Maine circa 1880. I once had some stereo view cards of Deadwood S.D. from around the time of Wild Bill Hickock. I sold some of those for $200.00 each. Photos of unknown, regular folk don't bring a whole lot.

There is a market for the old photo's that picture children with toys, dolls, pets.
Town photos of main streets,railroad depots are also collectible.

How do I get my looked at

We identified people in old photos by looking at ages and clothes. That family pic looked like it was late 1800s, the ages and sexes of the kids was a match with these ancestors. Then, we could recognize some of them in other pics.
