What you have is a Set of English Penny Coins being a normal and a cut out one along with a shell that perfectly nests over either coin.  The instructions give routine for Hong Kong Coin, Half and Chinese Coin Xpo (regular half not included), Coin On Finger Routine, Coin On Hank Routine, Penc-Off, Steve Dusheck Routine for Coin & Cord.  The shell is very well made in that the inner circular opening has a rim which conceals the cut out English Penny when nested together.  Includes illustrated instructions.  Condition very fine.
