Lovely coin Carleroo! And very nice old toning. I'm sure you wouldn't, but please don't clean it!
I'm really new to collecting. I just wondered where you can send coins off to be certified as I'm sure I'll get hold of some I'm not too sure about.
By the way, I live in Ireland.
Apologies for jacking Carleroo's thread, but it depends what you mean by 'certified' Sheen.
People use the term to mean slightly different things. TPGS do what it says on the tin; they offer a grading service. In countries where graded coins are part of the market, that's important. They also identify and 'certify' a coin is what they say it is and encapsulate it (put it in a protective 'slab').
Now in the UK most people don't slab their coins. And until recently, very few bothered with the 'certification' either relying on their own knowledge, the dealers they bought the coin from or from knowledgeable others at clubs or forums like this.
It costs to slab (£10/€12 to £20), so only really worth it for coins with a value some multiples of that, otherwise if you ever came to sell you risk not being able to recoup the cost.
So. If you plan to collect higher end coins, it may
be worth it. But buying from a reputable source is more important.
If you want to protect the coin from damage, fine. But there are cheaper storage options than a TPGS slab.
And if you want the reassurance that your coin is what you think, well, we (as in people here on CC or other coin forums) can often do that (obviously we can't weigh your coin or inspect it other than from a photo) for free!
As for TPGS, some attend the larger shows. Not sure what coin shows you might have in Ireland? Others you'd need to post your coins to. GCS is UK based and have huge expertise in UK (primarily milled, they have only just started grading hammered) coinage. PCGS and NGC tend to use UK dealers to whom you can send a coin and who then forward it for appraisal. Websearches will give more details of all of these. Bear in mind US TPGS' expertise is US coinage. They don't always get it right with UK ones. And there's the rub. In the end, it's all down to someone with knowledge doing the appraisal.
