I don't know much about it other than it is collectable. I picked up a brick of it at the Memphis/Germantown, TN gunshow last weekend. I spotted it on Friday evening and the asked price was $75.00 for the full brick. Sunday, the dealer that had it walked up to me and asked if I was still interested in it and said he would take $25.00 for it. I broke up the brick and sold nine of the individual 50 round boxes for $10.00 each. I kept the brick sleeve and one box for my personal collection.
Hope this helps.

Edit: Check that, just reread your post. Mine is 22 LR, not 22 Short. I've never seen S & W 22 short.
