It says on the site that it's from around 1894.
To find out the value, you'll probably have to get it appraised by a professional. Each piano can be so different, even though it might have the same date. It depends on not only the age, but also the condition it's in. Is the soundboard cracked, what is the finish, the strings and hammers, the shell of it. The peddles. Can it even hold a tune?
If you are looking to sell it or insure it yoou'll have an easier time getting an appraisal. Insurance will make the cost of it higher than it actually is, as they do how much it would cost to replace it, plus some for safe measures.
Best of luck in finding out the value. I'll keep my eyes open for your posts. Maybe I'll find the value of mine as I try to see if i can help out with the value.
