I made a recent trade with a poured style 10oz bar, basing the price on about $420US/$520NZ recently.
Most sell for $2-$3/per oz over spot. There are some rarer versions that sell higher The smaller poured engelhards sell for big money. the 2oz is an easy $1200.
You just have to fish in the right hole. I paid $1 over spot for 2 of those 10oz'ers, and the other 3 were between 2-3 over. The 10oz are very common in the US.
About.Ag has a site dedicated to silver with a very extensive identification of Engelhard bars he is building an great resource to share check it out it is very cool
