There is a reason that no one is responding to your question. It is because the population of E107 cards is unknown. They are certainly very rare. Some cards have as few as a couple known to exist, while others have 10 or more known to exist. The key here is "known to exist", since most of these cards are in private collections, so there is no way to know the true population. Anyone who states an actual number would only be guessing.
Where they will end up is another wild guess. I disagree that they have taken off lately. The prices of E107's have been climbing steadily for years. In fact, I think some recent auction results have shown a slight leveling off on the set, with a few exceptions.
