This has been overcome by engraving characters on the opposite side of the surface of the private key to ensure the private key is 100% not readable.
The only way to obtain the private key is by actually making minimal physical damage to the coin itself so any tampering is evident making the coin possibly the most secure on the market.

I'm not quite clear how this works.

The 270 is the amount to be paid upfront in the pre sale and the bitcoin can be paid after manufacture.

A lot of people got burned with the Coinographic preorder, perhaps it is better to make the coin first and then sell them.

Hi not sure what happened with the coinographic to be fair why did they take pre orders? I am 150% confident the coin can be made and how to do it. Also I have another coin that will be in production soon that will only be sold after it is manufactured. the reason I am pre selling this one is because of the extraordinarily high labor, time, travel and effort in producing them and the concept. Also with the fact that they are a high premium coin. If it was a regular physical bitcoin then yes there is no need what so ever but this one is different.

Also there will be 2 surfaces facing each other within the coin. One with the private key on and the other with 'gobbledy gook' on so you can not read the private key with any x ray or modern scanner.
