I've got 5 of the total 500 Physical WDC Antaui coins from 2013 that I'm selling, and I'm certainly not gonna let them go for cheap.
I'd be interested to hear your price for one of the Antaui coins, either buying one or trading for other physical cryptos.
I'm not so sure at this point. I'd probably sell them all together for around 4 BTC. More if I had to split them up.
