Why slab them? The cost of the slabs exceed what you paid. Slabbing such coins serves no practical purpose, but in the end its up to you.
https://www.ngccoin.com/submit/services-fees/ancient-coins/ It costs $25 plus shipping for NCG’s cheapest (slowest) ancients service. They won’t guarantee authenticity. If they doubt it, you’re out the 25 bucks. Before you spend the money, check eBay. I’ve purchased slabbed ancient coins on eBay for around $20, so slabbing doesn’t necessarily increase the value of the coin.
Now that I think of it, didn’t Harlan Berk launch a free authentication sticker service recently? That may be a better option for you.
it doesn't assure authenticity. Just to clear something up... While NGC will only encapsulate coins they believe are authentic, they don't claim those rulings are necessarily accurate. Where ancient coins are concerned, NGC only guarantees their grading. Theres much of a debate regarding some of their grading NGC neither claims nor certifies that coins they slab are authentic. As stated at the following page from NGC's site, "...due to the inconsistency of opinions on these matters in the marketplace, no guarantee is made or implied about the authenticity of coins graded by NGC Ancients." That statement pretty much sums it up. NGC does not claim that a coin in one of their slabs is necessarily authentic. Their encapsulation and labeling should not be thought of as a certification of authenticity. It is therefore a mistake to suggest that an encapsulated coin has been guaranteed authentic by NGC. https://www.NGCcoin.com/specialty-s...e-grade.aspx I have seen fakes in NGC slabs before. its rare but it does happen and then you paid all that for nothing. I would rather have a coin OUT of the slab, to save money and to have it in my hand if I wanted to. So as I said, it doesn't assure authenticity, all it does is give you a higher chance that it is authentic . If you spend a few years talking to experts you can notice the difference between MOST fakes and most real ones. I have only been doing this a couple years and I am a fast learner but I still have MUCH to learn
here here I like ancient coins in my hand to know that a historical figure could have had this same coin on his person if I want to see ancient coins through glass or plastic I will go to a museum.
