Royal Flush
I battled with this before. It depends on your outlook and what makes you happy like @Jeevansluck said. They were all produced to be played with (outside of collectible singles I guess) but the collectibility of this hobby changes things. No different from other big collectible hobbies such as toys or cars. Do you want to play with that rocket-firing Boba Fett or would you rather it retain its $150,000 value?What I don't understand is why have a set you'll never play? What are you keeping them for? Why not just collect singles, or barrels (if you want to see face and side profile).
I expect you know that eventually you will get all your chips in play.... just maybe infrequently.
Life is short, and there is only a very small group of people who appreciate poker chips like this forum. If you don't use the chips, who will?
I used to only collect and not play mint sets, but once I returned to the hobby I realize I would get more enjoyment by playing them.
