Video of my magic Trick - The Vanishing Penny !, How do I do it?

I start with a normal UK Pound Coin and a UK Penny coin.
I place a glass over them and the penny magically vanishes !


1) I start zoomed in on the two coins so you can see them clearly.
2) I zoom out and show the glass is normal.
3) I place the glass over the two coins and the penny vanishes.
4) After I remove the glass I zoom in close again and turn the Pound over a few times so you can see it clearly.

Please note This is NOT a camera trick or video editing trick.
The glass is a normal half pint glass.
The table top is solid wood.

Clever !

Thanks
