I think reason for this very low stamp value is because
1) There are lot of other things to do in this modern technology world than to collect stamps.
2) There are lot of forgeries in stamp collection
3) Shill bidding is way to increase price and fool new collector.
Now you need to decide what to do if you are new collector. Whether to start collecting Einstein stamps or Churchill stamps and get regret about collecting or if you are existing collector than forget about "what are my stamps worth" and just don't think about it, because it's worthless.!!
You will not able to justify your time in selling this stamps because it's not worth your time.!!
