How do i prove i sell real gold?

[barbipat]

Hi everyone,

Ii have intention to sell some personal gold items on ebay and since they are quite expensive items  i am a bit scared of being ripped off if i do some mistake so to cover myself i would like to ask if anybody can give me advices on few things

1- what is the most safe postage method to make sure post does not lose it  and customer customer does receive it ?

 2 - some of my items are very common models and because of that there are many replicas around so my question is how do i prove that i send the authentic thing?

for some of my items i do have receipt boxes and paperwork but i don't think the paperwork makes the item authentic so what are ebay rules around that?

would appreciate some advices

Barbara
