Thanks for all the help! I really appreciate it! I will upload some pictures once I get things a bit more organized.
The good news is in doing some more research, I've found out the Angola Birds and Mozambique Fish were both sets that created some excitment in the international collecting world in the 1950s. They do have Scott value of about $600,
ebay sales about $125.
The Postmasters of America series with Silver Medallions have some value too, largely because of the value of Silver right now. I've seen those sets on
ebay with bids at $300, which is nice.
I've also found some resources to match the CCCP stamps, and discovered I have the SPY series, which is kind of cool...no value, but cool. I have more research to do on the others.
I've since found mint stamps from "NORGE" which I think is Norway, from the 1950s also....so I'll check those out.
It appears my Dad was able to buy nice mint stamps before he married my mom and had kids! After that, it was mostly FDCs and found used stamps....but many of his have nice Cachets.
I have to say, though, I'm smitten now. I think it will be hard to part with any of them, and I want to sort through the bags of used stamps from all over the world that Dad had too....
It is a bit overwhelming, and he didn't seem to have a focus for his collection. I think I'll choose a topic I like and continue to collect/investigate in that vein. (Music, Space, Dogs?) I'm also a coin collector, and need to do the same with that collection.
Stamps and coins are beautiful, but a collector never really gets what he puts into it.....you have to collect for the love of it....
I'm sure I'll have lots more questions. Hopefully a newbie won't annoy people too much.
