Starting A TPG

i highly doubt you can start your own grading service, tens of hundreds have tried and failed.

and then the cost of the equipment, the plastic, ect.

your service will just turn into a basement slabbing service.

I don't think it's a good idea, unless you have unlimited money to invest in equipment, staff, advertising, etc. and are able to ride out not making any money for a number of years.

with all of the above. Please don't think people are being arbitrarily negative. There are probably just too many obstacles to overcome. Now maybe if you presented a plan with financial backing and a lot of numismatic expertise..........

The prices for PCGS and NGC coins are insane compared to what, SGS?
I have to admit, the thought crossed my mind at one point.
Here is the deal, the big 3 would crush you where you would never make it off the ground. Then look at PCGS for example, tons of name recognition in the Numismatic world.

If you think their prices are insane, wait til you find out that if you want a holder design that is distinctly yours, the injection molds cost $10K each and you will need at least three of them. On the other hand if your service fails you can always sell shells to other basement slabbers.

Yes and no from me.
No because your just to late to even attempt that. If you go to Google and type in TPGS's you'ld find there are already a real pile of them and many that Google doesn't know about. This suggestion is sort of like what happened to the many people that opened up Stores for selling, buying, renting VHS and BETA tapes. After all the big store chains started doing that, TV adds for that, articles in newspapers, then to try to start a new store was just to late and most went out of buisness. Same with TPGS stuff, just to late.
Also, just where would you start to dump all your finished products. ebay? Coin shows? Local coin store? Not many would want yours if they never heard of yours.
HOWEVER, there are places that sell the plastic holders cheap. You don't have to do anything special for sealing, just use Super glue. You do not need experience grading since many of the slabbed coins I've seen look like they were graded by a drunk. And t hose little tabs that explain what is inside the slab? Just use a computer printer. Doesn't have to be fancy since you would probably never sell them anyway.
If you have nothing better to do, lots of money to spend, a place to make them, no expectations on success, why not.

I personally think that NGC and PCGS have pretty fair prices for what I needed. I had about a dozen raw Indian Half Eagles, one of the most widely counterfeited gold coins. I paid between $300 and $350 for all but two of them. I joined for this year only and now all of my Half Eagles are hermetically sealed and graded, but much more important, they are authenticated and guaranteed forever. Not only that but I bought most of them at a dealer estimate of Extra Fine and all but two of them graded Almost Uncirculated, and most of them AU55 and AU58. I had all of them put in the new Scratch-Free Edge View holders and my collection is nicely packed in an NGC box. I used to have a bunch of coin flips rubber banded. Now when I lay them out it is a beautiful sight. If I ever go to sell them (which I doubt) there will be no arguing about exactly it is that I am selling. I was lucky enough to buy a mint state Half Eagle for $400 on an ebay snipe, so between the free submissions that NGC gives you when you join, and the $400 in value above what I paid for my mint state coin I have a total of $75 wrapped up in all of my fees including shipping. All in all one of the best investments I could have made to add value and safety to my little collection.
