OP made the right choice, v impressive sight to see, almost a million bucks in my local currency (CAD). What a time to be alive 
I think we are rapidly approaching (if we haven’t already reached) the time when the 25 BTC is simply unsaleable. The risks for everybody concerned are just too high. And I think it won’t be that long before the same will be true of the lower denominations. Hell, if BTC reaches 100 K I’m not even sure that the one BTC coins will be saleable anymore.
The coins will always be saleable, but it's a matter of being able to transfer said asset safely.
