Do you think the Forever stamp will be used forever?

Question

The USPS unveiled the new Forever stamp which costs 41 cents cuz once again postage is going up in price.
But they hope to have this stamp will eliminate people using 1 cent and 2 cent stamps to make up for new rates.
They have the Liberty Bell on them too. How cool is that?

Answer 1

That it will be good for a long time I do not doubt, and I will be investing a fair amount of money to purchase probably a 5-10 year supply, but am not too sure if it's a worthwhile investment beyond that.

While the stamps will after some time gain an advantage over cost of living increases, the nagging if tiny suspicion that someday the USPS could declare the stamp null and void (say after 80 or 100 years) persists. They probably won't, but a slim chance exists. More believably there exists the issue of destruction or decomposition, I just don't know how long they will last, and we don't live forever either. Thou I do think you'll see one here and there for many years to come after the first 5-10 have gone by, they'll become rarer and rarer but after 20 or 40 years you'll likely find very few in use.

As for forever, I can't see one making a round in say 500 years, but I suppose it's possible, perhaps better at that time to sell it as an ueber rare collectible :)

I don't see any of them making it to 5,000 years from now thou.
Per the definition of forever, that is, but it is cool, I like it.
