Recently I've been seeing people try to sell untextured Blocks, for diamonds no less. this was strange to me and here why.

I been playing on this server for a while now, (maybe 2 years, I lost count). Back in my day, when a certain update came, some block didn't have a texture after the update, hence untextured. What's important is when this first happened people tried to sell them for very high prices, only to realize that they weren't worth that much, mainly because everyone had them.

But since then I can only imagine the amount of untextured blocks has gone down since I dont know a way to produce them. So there worth has gone up.

So my question is how much does a untextured block typically go for? Ranges are good. For instance spawners go for 6-8 diamonds.
