I think I will risk it for the biscuit and see what it looks like in hand. It's very reasonably priced at about 3x the value of the silver content including shipping. So wouldn't be a major upset if it wasn't a micro o. I think I will get it just out of curiosity and see what it looks like in person. Based on these pics the mm is hard to makeout, but it looks slightly tilted to the right so it could be a possible VAM 31. Only way to see if better I guess would be to purchase it.
It was $63.75 including shipping. So priced about right for a regular 1899-O. I guess we will see what she looks like when she arrives on April 12th. I will update this thread with new pics once I have it in hand!
