Now, I'm fully aware of how the value of some figures increases greatly over a long period of time. And if I had any rare figures, I certainly wouldn't open them. But I've been working on a collection lately, I've had high hopes of turning into a really nice display. However, I have been strongly advised not to open my Marvel Legends and Spawn figures from now because they are going to be rather valuable in say 40-50 years. Like they would be a really good investment. I've been giving both ideas strong consideration, and I have decided if I should for the display, or store the figures away for a few decades and potentially profit from them later in life. My question is, will ML, DC & Spawn figures really be that valuable in the future, or is it okay for me to go ahead and make a display once I've built my collection?
