So.. Yeah, I Inherited A Collection

So I have my grandfather's stamp collection.
A few thousand stamps, mostly from the 50s and 60s. The vast majority are from the Eastern Block (Soviet, Bulgaria, Romania, etc.), but some are from distant countries, some of which don't exist any more under the same name. Most have floral and fauna motives, I don't know why...

The question is, are they valuable? I know I'm not getting rich, but my parents tasked me with figuring out if they have any value. If not, we'll obviously keep them, some will go into frames (especially the ones with wild animals and plants).
Here are some...

Links not available

Since the link doesn't work, here are some pics

You'll get a few € if you put things like this on ebay, but very little. Most of this material is of the type mass-produced after WWII for the stamp-collecting market, and has very little financial value. Sorry!

If there's some earlier material, would be worth showing that here.

I'll post some nice pictures once I put some of them in frames and decorate the weekend house.
Thanks you!

P.S. Let's see if I get hooked...

Not enough monetary value to be concerned. Wall paper literally in this case.

I like the framing idea

Nothing to add in regards to value, but there is one stamp that is slightly more interesting than the others. It's in a frame by itself and is a small blue stamp with the letters C.R.I.C. and some serial numbers in red. It says Calzado Cubano, which means Cuban shoe factory, and the words cinco centavos (five cents). This is quite clearly not a postage stamp, but has some sort of non-postal function. With all the privations that Cubans have suffered during the years of the US embargo, it's possible to suppose that some sort of rationing system has been in place for the purchase of such necessities as clothing and shoes, so I wonder if it's some sort of ration stamp for the purchase of a pair of shoes? Sort of like the savings bonds stamps kids used to buy at school, which, when the book was filled up could be exchanged for a savings bond. Does anyone else on this forum know?

The Bulgarian Esperanto label is kinda neat. Probably not valuable $$-wise though.

Love the stamps. No idea of worth, but thanks for the photos! Where are the stamps with "Guinea Espanola" from? Would translate in to Spanish Guinea; but need an education beyond that.

Spanish colony on the west coast of Africa. Became Equatorial Guinea after independence.

Another country which has undergone a name change is Upper Volta (Haute Volta in French which is how it's shown on the stamps) changed its name to Burkina Faso in August 1984.
