FWIW, I'd have said right around $200-ish. $500-ish? Not to me. But for generic gold dollar love token money ($90-ish), that was a steal. Note it was not listed in the Love Tokens category- only gold dollars. The seller lost money doing that, and that's likely why you saw it first instead of me. Great grab.
I, um, wonder if it's the same guy? I saw this one on eBay a while back, I think, and nearly fell over -- not only a Bechtler love token, but one that carefully avoided effacing the peripheral legends! And Saturday, I got to see it in hand.
