Absolutely. If you've got a gem like that, people who don't even need one will scratch and claw for it just for its trade or resell value. (A Galaxy Explorer can sell for $200 or more in an auction and is considered a "holy grail" of Space sets.)

Note that you'll get a tad more money if you sell off one every three months, but if you do that, you're investing your money poorly -- why keep $80 tied up in something for six months that you don't intend to keep?

Keep your inventory low unless you are waiting for that perfect trade to come along.
