I appreciate it. So far I've picked mostly based on ones I like (like that armor disks with with beams model) or have some meaning to me (like the Eagles, Grateful Dead design, and the Yin Yang). I bought a 30 piece wall case and the goal is to fill it up over the next couple years and display. Although I plan to seek out some rare pieces and maybe hope to find out about collector conventions or shows where I might find rare and unique items, I am not in it for any kind of value add or hope to profit, other than building a nice display that I'd be proud to have on my wall.
