Conjecture. No evidence whatsoever that that is the case. The government employees stole this woman's property. Period.
Not conjecture. No 1933 gold coins were publically issued. Some were stolen and sold on the black market. This woman's dad admitted to selling some of the stolen coins in 1944. Now more show up, passed down from the admitted fence. Q.E.D.
They are either stolen from the Mint or are counterfeit currency, either of which case deserves confiscation. If the latter, she deserves arrest as well.
