That's quite a gamble in hoping for a repeat of the 1999 Sets.....

I doubt you'll end up actually "losing money" in the long run....but adding in all of your efforts.....+ shipping/postage/other costs.....WOW ! ..... 40 Sets huh ? Whew !!
Keep em' intact and wait for the chance to unload em.......could be several years though.......or more.
Make sure you don't store them in a humidity area too...... because it would
REALLY suck to pull em' out in 6 years and notice some bad tarnishing developing.....that would deteriorate your "profit margin" as well as the coin ! .....
