Locking $2.85 Trick with Brass Bang Ring by Johnson Precision Magic

For the connoisseur of fine magical apparatus. Same effect as The
Locking Dollar Thirty-Five trick but using two silver dollars, a half
dollar, quarter and a dime. Everything vanishes except for one silver
dollar, and that can be examined with a magnifying glass. Includes a
dollar size bang ring. Easy to follow routine also included.
