The number of mule dollars released into circulation is not known, but numismatic experts estimate that there are no more than 20,000 pieces available, most of these being in circulated grades. PCGS has been grading them for many years and has assessed the condition of over 500 examples. Of those, just five examples were assigned the grade of PCGS MS64. Four of those five coins are currently impounded in collections, presumably for the long haul. Based on the population profile, coins in MS64 and MS63 must be considered rare, and are in the top 3% of coins known. Coins in lower grades can be considered scarce.

For a time, the 2000 mule dollar traded at very high prices, with even somewhat circulated examples selling for over $1,000 in Australia. However, prices for mid- and low-range coins have fallen in recent years as mules continue to be discovered in change. As those coins tend to be heavily worn, they sell for only a few hundred dollars and are an affordable option to the collector who has not yet been lucky enough to find one in change. Condition-conscious collectors can opt to obtain coins in MS62 or better, which are scarce, but not rare, while the connoisseur collector should aim to acquire an example in MS63 or better.
