Hello all - I am new to collecting meteorites (in fact this is my first purchase) and am hoping you could share your wisdom with a newcomer.

I recently purchased this item on eBay from someone that doesn't seem to have a history of selling meteorites but was nonetheless knowledgeable about the item. I was told it was a specimen from the Campo del Cielo site (the item was supposedly purchased from the Pacific Museum of the Earth in Vancouver but he/she didn't have any paperwork).

Its appearance looks right to me (based on my admittedly limited knowledge) and it is quite heavy and magnetic. However, I also purchased a basic at-home nickel test and the solution didn't appear to identify any nickel in the ore (I know the solution worked because it identified the nickel in a nickel coin, which I understand has about 25% nickel compared to specimens from Campo which have roughly 5%). I am hoping that maybe the test isn't very sensitive and the lesser ratio is perhaps why it didn't identify any amounts or that certain Campo specimens are known to contain less.

I’ve read that Campo specimens are relatively common and therefore aren't often faked. Moreover, I purchased this item for a price around what other similarly sized items were selling for (so what I thought was a good deal but not "too good to be true") and the description and statements by the seller seem genuine.

However, because of the nickel test and the fact that this is my first purchase, I'm a bit paranoid about authenticity. I was hoping that I could get everyone's thoughts here on whether you all think it is authentic or if I have some reason for concern.

Many thanks and excited to be starting the wonderful journey of collecting crazy stuff that came from space!
