4 pages to answer this?

Easy:

Use an axe!

 

How utilitarian

C4 is so much more efficient.

 

Acid, of course.

 

Well did you ever free the coin from the capsule?

 

You are correct with a partial answer inasmuch as the thermal coefficient of plastic expansion is greater than metal.

The phenomena may/will be seen/experienced as elongation/expansion/buckling of plastic siding/rain-gutters on a hot day.

A possible solution is to turn the capsule open side down in a transparent bowl with water being slowly heated.

Water may be a pseudo-lubricant, and even heat distributor!

The captive gas above the coin should/may expand helping push the coin out downwards, while the circumference of the plastic increases, possibly releasing the coin because of gravity/coin-weight. The coin may be viewed dropping, unless the diameter has been distorted to egg shape.

A more probable solution is to slam the open end of the container downward on a hard surface, with a snapping action, where kinetic energy caused by the moving/stopping coin weight may simply release the coin if starting with a small vertical distance moved, to an increased distance and speed.

Watch your fingers when using this approach!

There are other non-destructive methods if neither of these work, but the 2nd suggestion is the simplest if the container is still round.

JMHO

 

And if that doesn't work, then put the (soaked) coin and capsule in the freezer, and wait for the contracting plastic to crack, or the expanding ice to shove it away. (You could try scoring the capsule first, to create weak points along which it would crack.)

 

What if the coin cracks first? Cal

 

Hey @Gam3rBlake any update? Inquiring minds want to know.

 

Pretty sure that won't happen, even if you've got a cryogenic freezer...

 

I notice the OP has gone missing. She used to post quite a bit, I hope she didn't take the suggestion to use explosives.
