These are all heat-sealed this year. I am a Mint on Card collector and really wanted the coins. After thinking about this, I managed to find a way to save the integrity of the card and remove the little stickers inside without damaging the star case (too much).
The solution? I used a pen knife and cut through the Star Case and the Cardboard insert, beginning at the top of the Proof of Purchase and cutting toward the bottom on each side, then cutting through the star case across the bottom. DO NOT CUT THE TOP SIDE.
This creates a flap in the STAR CASE and the Cardboard Insert. Through this flap, you have access to the plastic bag taped to the inside of the cardboard insert. One simple cut through the bottom of that bag, and you can leave it taped to the insert, and slide out the redemption certificate in one and the stickers in all 6.
The stickers in mine were all on the inside side of the baggy, meaning that through the flap you could see them near the blister coffin of the figure. I slid them with a pen knife toward the slit I made in the bottom of the baggy and pulled them out, leaving the certificate, tape, and bag pretty well intact in 5 of the figures.
Pushing the flap closed then, a simple piece of clear packing tape, seals the opening again...and there you go.
You can then attach the 6 stickers to one certificate and get the coins!
The figures and star cases then, look almost as good as they did when they came out of the case!
AND...You don't have to cut open the STAR CASE because of the damn heat seals...
