Only Graded 

Really good service! Thank you!

Wouldn't reccomend for people who are already experienced in the collecting hobby, but is OK for new collectors as it is on the cheaper side. Generally though, wouldn't reccomend because the slabs are generally poor quality. As someone who has two and saw hundreds at comicon on display, they consistently have crumbs and bug legs sealed inside the slab. Also due to the sleeve cards *appear* to be put in before being sealed, the cards have bubbling all over them. Also due to how the cards are sealed in, they are extremely difficult to get re-graded at a different service if you are unhappy with the quality of the slab. Grading is also incredibly generous, would not reccomend AT ALL if you are doing this for an investment as they hold very little to no value once slabbed

Beautiful slabs, better than PSA by far time wise and quality wise, I will defo be using again! I got a ghost rare 10 although I sent a PSA in for remarking and received a lower grade but I feel it was a fair call

Bought a signed card graded by this company went to cross grade with psa
& found out all signatures was faked

Even though only graded authenticated them took 3 months to get refund

Terrible customer service & blamed it on me 🥴 company is a cash grab nothing more

I placed my order on 1st of March as express 5 days turnover it’s now 30th of March? I’ve been told false tracking details then I’m told there machines broke? I’ve asked for tracking number multiple times and still haven’t got that. I haven’t heard anything of my card or when estimated delivery will be? I run my own business and this is poor.

Sent a football card in for grading. The delivery was fast, the grading was 100% accurate (it was a 5 all day). The slab is surprisingly beautiful. Will definitely be using again.

Probably the worst customer service from ANY company I have seen in my lifetime.

Hair, crumbs, fluff and more in my slabs. Card grades do not seem accurate. I sent a few cards in (some knowing they would get a 6 or 7) they were then graded a 10?!

Still awaiting a refund. Once the refund is processed, I will think about removing this review. It's been 4 weeks and counting and no refund.

Hair and dirt stuck inside slab !!!!! card dirtier than when sent in glue marks on slab ?

Grading Company on the up! Slabs look soooo good, friendly and quick customer service! Best in UK for price and time! I'll definitely be using again! Cheers!!!!

Extremely quick service provided with my cards turned around within a week. The OG team were super friendly when dealing with my queries.

Most importantly, the graded slabs looks unbelievable! Would use again.

Amazing company! Would recommend to anyone! So so helpful and amazing products!

Great amazing experience Start to finish! Best slabs on market and I’m excited to use again!

Five star experience from start to finish m! Sent in cards and got them back well in time! Best slabs in the world period and no more sending overseas as you have the best company in London!

Totally worth it!!
Received my submissions back rapid. Customer service is on point can’t complain. Looking to grade all my cards with these guys!!

Definitely recommend

Got exactly the grades I expected after doing extensive research, came over a month early and the communication was just perfect. Best looking slabs out there and with their new shop in Birmingham, advertisements, attending events and cool slabs with super fast grading, I believe OG will 100% become the best name in grading cards. No need to invest in psa anymore

I had lots of questions about grading and their sale team was so nice and helpful! Definitely will send more cards!

Super happy, received my cards back in extremely competitive time. Very well presented and good communication. Best in UK market

Brilliant service so far. I bought an Only Graded Pokemon card off Ebay and after looking around their website I found it had been graded wrongly according to their grading system. I contacted them and they said to send the card in and they'd re-slab it. This took about 8 days which I thought was really quick.
They also recently had a Black Friday sale so I sent 10 cards off for grading on 29/11/21 using their 60 day service. I got the cards back today on December 9th!! From sending them to getting them back has taken about 11 days. That's lightning quick! Will definitely be using them again. Not just for the quick service but the slabs they use are quite thick and not thin flimsy things like some other grading companies use. Thank you.
