Coinage Clause
ARTICLE I, SECTION 8, CLAUSE 5
The Congress shall have Power To...coin Money, regulate the Value thereof, and of foreign Coin....
Only regulated coinage (money) is illegal to counterfeit.
All other forms that have an apparent value placed on them by government authorities are simply regulated as “market value” or “barter value”.
Of any form, ask if the value-authority is derived from Congress.
[HINT: Congress did not create/value a Vaccine Passport]
If not, it is simply a barter tool.
