Hello, in the May 22 E-Sylum, article "History of Disney Dollars," you mentioned that it would be nice to see someone update the book through the last series issued this year. Charles Rodgers (spelled with a "d") issued a 2014 edition of his catalog, although few were sold before he died that year. Some Disney collectors do not know of its existence, and a Heritage lot states that the Rodgers book ends in 2009.

I bought mine from blackmountaincoins.com and see that they have two copies left. $45 plus shipping is high for this short, crudely printed book, but it remains the essential reference in the field.

Many thanks for all of your work each week. I copied the May 22 issue into Word and it ran 102 pages. This is an extraordinary achievement for one man.

The Disney notes became a collectible soon after they became a currency. They were conceived by Disneyland's first president, Jack Lindquist, with images of Mickey Mouse, Donald Duck, Goofy and Pluto, as well as park landmarks, and it was apparent immediately that not all would be redeemed, but many would instead be retained as souvenirs and collectibles. They were a hit from the start, with reports of transactions as high as $10,000. The notes exist in denominations of $1, $5, $10, $20 and $50.

PCGS Currency has graded more than 20,000 Disney Dollars in the past few years. Laura Kessler, the grading company's vice president, says that they have become one of the most competitive and popular categories in the PCGS Currency Set Registry program. She was surprised by the decision, since Disney Dollars are more popular than ever among collectors, and the Disney Dollars held by collectors and not used create almost pure profit for the company that reported a net income of $8.38 billion for the 2015 fiscal year.
