I like coinographic's coins, but he made a mistake by not having the LTC address visible on each and every coin. There is no way for any of us to confirm that the coin you're selling us is still loaded. Coinographic sells replacement holograms. How hard would it be for someone to purchase a dozen coins, redeem half of them, put a new sticker on the back, slab it and sell it as if it's fully funded? I'm not saying you would do this, but the fact is there's no way to guarantee the balance of any of these coins.
I agree that that coinographic should have made the window.
Nevertheless, the whole point of the security sticker is that it is tamper secure (I assume that coinographic's hologram are tamper secure?)
As a crypto coin collector you have to rely on that there are no "replacement" security stickers floating around, that would cripple the whole concept.
If you could break the security hologram and get a copy of the private key, and restore the hologram with a "replacement sticker", you don't even need to redeem the coins right away, you could sell them, and "empty" coins after they have passed on between a few new owners. Personally I always exam the hologram with a magnifier when I get a new coin to make sure that there is no signs of breach, I also only buy 2nd market coins from people I trust.
When that is said, I can vouch personally for wafdawg, I do not believe he would ever deliberate sell a unloaded coin under the impression that the coins is loaded.
You can buy from wafdawg with confidence, no doubt.
As for coinographic, I have no experience with them, but I do note what smoothie has stated about his experience with privatekey management, which is worth taken into consideration.
