I am aware of what I believe are five extant copies each of the three rare MLAS cards and can't tell if these bring each pop to six as I don't have great scans/back scans for some examples. I got into the weeds on the origin of some of these awhile back, curious if anyone can shed more light on the current Heritage offerings or overall. The summary of origin conclusions are at the end of the post:

I think there's an excellent chance the Roberts gets to $150K or so, not sure the other two will get to six figures but it's going to fun to watch.
