Hello !

 

A lot of grading books mention a pinpoint light source , what is this .

Also an incandesent light bulb. Is this a normal light bulb if yes hoe strang (how many watts .?

What is a Tensor type lamp ?

 

Is there a way I can tell NGC to move a coin to NCS if they cannot grade it?

Normally they send it back and I have to send it again this time to NCS .

 

Thanks Gunter

I would recommend using a single 75 or 100 watt bulb in a darkened room when looking at coins.

 

A tensor light is a special light bulb that gives off a full spectrum of light.

 

If you have any doubt that your coin may not grade with NGC, it is best to submit the coin through NCS Details Grading. If the coin will grade with NGC, you will receive it in an NGC holder. If the coin will not grade with NGC, you will receive it in an NCS Details Grade holder. Your fees will be the standard rates based on the value and type from the company that actually does holder your coin.
