I think you're living in a time warp. So much of what you've mentioned in ths thread is obsolete and worse, incorrect and improper about verifying authenticity.
1) If the coin is in a authentic slab (verify by sending pictures to the grading company) then there is no need to worry.
The third party grading services do not authenticate via picture(s) sent over the internet. They do this with the item(s) in hand where they have access to analytical techniques to obtain quantitative information that can be used to detect anomalies with known specifications of their product and that of the original mint that made the numismatic item in the first place.
Both coins and slabs are forged, and slabs are also re-used outside of the grading services by sleazy operatives in their machinations to deceive and fleece folks.
2) Plus, opening an ngc case is rather difficult.
Any third party slab can be opened and tampered. The NGC case can be EASILY opened by an experienced tamperer/thief. Some generations of slabs are much easier to open than others. I've even done it myself when "cracking" NGC coins out for re-submission. It's well known that the two parts of the shell cleave neatly with the right tools and a little experience. Creating a fake ultrasonic bond is easy, too.
3) As for Bullion, you use something called ED-XRF spectrometers, which is part of a SPECTRO MIDEX, which we have. Most major companies and coin dealers have this On hand TO VERIFY gold bars without damaging them or taking them out of the Assay, that's the old way and in your delusional trust issues, you won't purchase online.
Apparently you are unaware of the limitations of your EDXRF equipment. It's only good detecting a few millimeters into the object at best. It may work on your wafers and most 1 Oz bars, but it won't work on anything thicker.

4) You are just as likely to be taken in person than online.
Unverifiable statement. This is indicative of ignorance and a shameless attempt to self-promote ones onling business. Yes, I have the same chance of being taken by a stranger, using an anonymous ID, living in a far-away place than I do with a professional at the coin shop in my hometown - not.
5) As for disputes, 6 months dear. You also can dispute with your credit card or bank or however you sent the money.
I'll take 24 months any day of the year over a 6 month maximum period to obtain a refund. Good luck trying to ever get funds back on a personal check payment once it's cleared!
6) You should read up. As I stated before, even the replicas are just slightly off. The tone of the logo, thickness of Assay Card and others. You can buy Bullion online, just do your research and be smart!
Evidence of an unrepenting liar proffering bad information to the numismatic buying public. Yes, I probably read as much as anyone about numismatics and forgery here on eBay. You don't think those who are hell-bent on fleecing you aren't burning the midnight oil to develop new forgeries? It's never the snake in the lawn that gets you, its the one that you don't see that gets you. Moving ahead with delusional blinders and technological faith is just too risky for a lot of folks, including myself.
I sincerely hope you have luck outwitting the International criminal syndicates that are involved in making and distributing a whole range of this nefarious stuff. With the limitations of your thinking and mindset, you've set yourself up for victimization and the creation of victims as your online buyers.
