Companies sell Santa Claus dollars by overprinting Santa. (example: https://santadollarbills.com/)

They are not cheap, $7 for $1 face value, but the Treasury has not shut the Santa dollars down and it's still considered legal tender.

Can someone legally print these Trump Bucks?

Have to be a little quiet.

As soon as CNN finds out about it, it'll be 'illegal'. Needs to be over and done before the MSM freaks out the US Treasury.

Or: make 'plans' to do this, with no intention of carrying them out, to freak out the MSM.
