I have two sets:
Hynix 4x16GB 2Rx4 PC3-12800R-11-12-E2
Hynix 4x16GB 2Rx4 PC3-12800R-11-12-E2
$100 for each set of 4. Pictures: https://imgur.com/a/9Huy2UC
I can’t guarantee they work since I don’t have a motherboard that will run them, but the seller I got them from on eBay was highly rated and these were pulled from working servers.
Edit: Added pictures to the post directly.
