Like I said before this is not true. I won at action a roll of 20 black text buyer funded coins. I have one for sale here: https://shop.coin.community/product/lealana-0-1-btc-silver-black-buyer-funded-rare-2/

There's no doubt these are rare coins and even rarer at the quality of yours with CoA etc. Unfortunately no one but smoothie really knows how many were made, but I can tell you I had 20 at one point, so there's more than that.
If anything I'd be sus of funded "buyer funded" coins. It's relatively easy to laser etch "buyer funded" into the hologram of a funded black text coin.
Congrats on the sale anyway, you got a very nice premium and this is hopefully the first of many crypto coins at auction houses like this.
nice auction!
I also got one of these black buyer funded (unfunded) 0.1btc coins, actually got a matching set including 0.1, 0.25, 0.5 and 1 btc
