There's the rub. There is an unknown, but significant amount of gold lost on the ugly love token. I wouldn't buy these without putting them on a scale, and then discounting for solder left on the 1873.
For $300, I might bite. You could honestly sell them at auction no reserve on ebay and make a little. I can see them going for about $180-190 each no reserve, starting at 99 cents.
No offense, but I always get a kick out of posts like this; not as much as I used to in real life though. Beyond the lost weight, which is an unknown, buying at would-be melt to sell at likely actual melt, even with a "small bump", and especially if the plan is to unknown Craigslist buyers suggests you must be a glutton for punishment. With that said though, sure, there absolutely are people out there who don't want to deal with the hassle or nonsense that often comes with selling such things in person, but the seller is located in a metro area of well over a million people himself, and is probably keenly aware of his off ebay opportunities. If I had to take a not so wild stab in the dark here, I'd say that the coins are likely on ebay for a reason, and that reason being he's trying to maximize his return.
At your quoted price, and potential plans, good move. It's not like it once was, and probably never will be again, at least in my lifetime - the days of average people having a stash of silver pulled from circulation over the years, or grandma's safety net gold coin are, for the most part, over due to how much came out a few years back - but there are opportunities out there for those willing to look and get their hands dirty. Lots of these guys offering to buy on Craigslist have no intention of paying melt, and would rob you blind if given the chance. If you don't already, try to find someone straight who will pay $X for X with no BS games, then compare anything you find and believe has potential to that.
