Where to sell 78RPM records?


I recently inherited a handful of 78RPM records. The collection is composed of opera, classical, and Broadway music on Columbia, RCA, and Decca labels. They are boxed sets consisting of 4-10 records in remarkable (for their age) condition; my father was very OCD.
I'm looking to find a good home for them. Anybody know where these could be sold? No Ebay.

Thanks in advance for any assistance.

I have to agree. Classical and opera 78s have little if any value. On the other hand, jazz, rock and blues can be worth good money.
Thanks to both of you. Money isn't the salient issue here so I'll look for some historical groups that might be interested in the donation.
