Need Help Identifying / Pricing 2 Bulgaria Stamps

Can anyone assist?

First one : Michel # 441 (year of issue : 1942)
Second one : Michel # 510 (year of issue : 1945)

Scott 413, 475

They appear to be very common. There could be some feature of one or the other that makes it more interesting to a specialist, but that seems unlikely.

They probably aren't often sold individually. They are the sorts of stamps that pass around in inexpensive packets of 50-100 mixed stamps.

All that being said, what little I know of Bulgaria ends at 1940, so I can't tell you if there are uncommon paper or perf varieties in these series, or an interesting cancel. Michel doesn't show anything exciting. (The 1942 is marginally higher valued, but not in any meaningful way.)

Still nice to have.

edit: By "Michel" I mean the general Michel Southern Europe catalogue.
