Featured Books from 18th and 19th century worth?

Ive found among many books that my cousin left me some that are really old. 18th and 19th century. So Im interested in more information on potential worth of these books.Here I attached some of those books,there are a couple of more.

Thanks in advance!

 

The German Lexicon is likely to be the only one of any interest, the rest are all routine religious works, which have survived in large numbers due to never having been read.
You really need to be in the 1600s for almost any old book to be sought after. Later than that it all depends on subject, and any subject is better than religion.
Language is also important, you'd sell the lexicon better in Germany, obviously.
Condition is also important.

 

There might be some interest in the Croiset. A copy is currently listed on Abebooks for about $50. No idea if that's just wishful thinking.

There may be some interest in the Hubners Lexicon. A different and much earlier Lexicon is listed on AbeBooks for $200. Yours is religious (and probably a later edition) but the other (I think) is not. Being a religious book won't help, but the frontis engraving will help if it is in decent condition (looks stained).

People will make allowances for the condition of old books, but it's still very much a consideration.

Books on religion survive more than others because people think it disrespectful to toss them.

 

"Disrespectful to toss them"... and they're never read.

The only one I'd want personally is the opera, and then only because of multiple friends over the years who were into opera. It's not one that's performed much these days.
