Hello, looking to start in the world of coin collecting
I have seen this coin and thinking of buying it: https://www.ebay.co.uk/itm/325240912077?_trkparms=amclksrc%3DITM%26aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20180816085401%26meid%3Da4ddc7ce90cc46e2accfa1e5505948ac%26pid%3D100970%26rk%3D1%26rkt%3D1%26sd%3D325240912077%26itm%3D325240912077%26pmt%3D0%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100970.m5481&_trkparms=pageci%3Aab20bb95-494a-11ed-92c5-5e5c9db862a1|parentrq%3Ac677631a1830a9f9331517b1fff03a26|iid%3A1
It may seem like a silly question so I do apologise, but with the environmental damage label, does that mean that the coin will continue to deteriorate in the slab or is it now preserved with nothing remaining on the coin to damage it further?
Thanks!
