Mountain Goat – Dinar Guru How long will we have to take our large 3 zero notes to the bank to exchange them? In 2012 the CBI told us in an article that these 3 zero notes would remain in circulation for at least 10 years once the project to delete the zeros is concluded. The US Treasury has still to give us investors a definite time span to turn them in for exchange. My only guess is this that these 3 zeros notes will be around for a very long time just like the US dollar has many very large notes but you hardly ever see them or hear about them, yet they are still legal tender. Having said all this. This is my simple answer – Get your asses to the banks as soon as you can and exchange!
