What would you pay for good quality LiFePo4 batteries 8 years old hardly used in a caravan but trickle charged and maintained the whole time. Would 50% of the original cost be too much?

Maybe 50% of current cost but not original cost. I'd probably walk away even then unless it's exactly what you want, but that's me. 8 years old, there's going to be some degradation. 25% to 30% would make it worth taking the risk to me, but this is all purely subjective.

That would be my concern. LFP are better stored at 50% SOC and unless I knew the trickle charged voltage I would be concerned enough to want to do a capacity test.
I have decided to buy these 6 x 50AH 12V batteries for USD $467. They are 8 years old.
Included is:
1 x Victron 12V 30amp blue smart charger which I will sell.
7 x 40W good quality, caravan type, solar panels which I will sell.
1 x 1500w pure sine wave inverter - will sell also.
Bus bars to suit - keeping.
I should recover around USD $167
Total cost USD $300 or USD $50 each
I figure 3 years & I get my money back - if they last.
Thanks to those who answered.
agreed, as posted in another treat..
my 2015 build plastic encases calb cells are still well above 80%.
do have to say it treat themwell and didnt stress them by over, under or to fast charging.
get yourself a good cell tester and see what they will give you
I have an 8 year old LFP that I always stored fully charged for 4 years before I knew better and it is still well over 80% capacity although I didn’t test it when new for a baseline.
Any simple DROK or other chinesium meter that will track Ah is sufficient to test for this purpose while using the battery IMHO.
