in my case I see the Disney dollar as a long-term investment as the example you say of the coins that were released in the first version in 1987, where Disney issued the Mickey $ 1 and the Goofy $ 5, which currently has a great value .
Granted, one could invest in dysneydollar and forget about them for a long time and then sell them for an average of 15 to 20 years, where they have more value for seniority.
That's the way to do it. Put them away and forget about them for 10 years, then see what they're worth.
