Wow, what a site
https://www.buckacover.com/I'm still wrapping my head around the valuation of FDCs. There are so many more variables than stamps alone. The stamp, how many stamps, what cache (if any), addressed or not, condition of the back (glue staining), subject matter, how many were cancelled.
Obviously some of these parameters are subjective, like subject matter, and I'd guess to some degree, if it's addressed or not.
But I'd think that if the cancellation matches the official release city, that's good.
The number of stamps is good (even better if there are margins with plate marks).
The value of the stamp.
The quantity of cache produced
The quantity of cancellations on that day of first issue.
Now with FDCs, you want it to be cancelled, whereas an uncancelled stamp is worth more usually.
Time. I know. More time...
Thanks,
