Is it permissible to collect counterfeit currency?
<p>I know that making, or preparing to make, counterfeit bills is illegal.  I also know that if you use counterfeit currency you can have problems whether you were aware of it or not.</p>

<p>I would like to buy or acquire counterfeit bills to keep for educational research purposes.  Is there a legal way to do this?</p>

<p>I am interested mainly in Polish Złoty as well as Euro and Dollar bills.</p>

<p>Generally speaking, if you can render the bills "unfit for circulation" then you should be ok.</p>

<p>One way to do this would be to laminate the bills in plastic, with an indellible label that states:  "COUNTERFEIT CURRENCY" or something to that effect.</p>
