Strange To Me Stamps

As I was sorting some stamps I came across these and found them quite interesting,does anybody know anything about them.I really want to know about the very first one because it looks like it has some kind of serial number on it.THANKSalso the very last one I have quite a few of these they look fake to me

The easy part is that they all appear to be Romania. The first ones with the serial numbers are probably Revenue stamps. There's a pretty good Romania Revenue stamp website. The scan is not clear enough to make out the writing which would be key to identification. A goodly number of the reainder are "back-of-the-book" postage due and various tax stamps. Again, I can't make out the inscription on the or detail on the last one but with the selvage attached, it appears to be genuine. I don't recognize the issue but then I'm no mexpert in Romania.

1ST stamp is cuba 2nd Romania 3rd 4th Bani and the rest Romania

The very bottom one is Germany, during the Nazi era, and it is imperforate, which is not typical -- in fact, I've never seen an imperf one. Get one of our German experts to check it out; it's probably in the Michel catalogue.

The set is Scott #B292 and B293

This is for the 12Th anniversary of the Nazi party. Imperf are the same value as perforated. Mint around $5.00 The used stamps are the ones to find. Used/cancelled are worth around $850.00

I know it is just a detail, but shouldn't it be the 12th anniversary of the Nazi party's getting in power in Germany? B292-3 is the last stampissue before the final collapse of Nazi-Germany.

Glenn I have alot of those imperforted stamps

Just in case you're confused, the stamps inscribed "Bani" are also Romania. The "Bani" is the unit of currency.
