You are correct with your assumptions, most of the VAM's are blob's die cracks, and minor stuff...all of which are not listed in the Redbook. The real varieties...0 over CC, 7 over 6, Dbl Die, 80 over 79, etc have separate listing and pricing in the Redbook. Some dealers do expect more for a coin, with a VAM number, but I am not one of those people. I would not pay a premium for a VAM coin! BTW...I am going to be in my Father's Family homeland (Scotland) in late September. Going to Glasgow, Laggan, Airth/Falkirk, and Edinburgh (also England and Wales). BTW...what is haggis? Is it any good? Ha,Ha! We are going to have a dinner in Edinburgh that has haggis on the menu! We are on a Trafalger tour. Haggis is a once a year meal for me at most and I wouldn't bother having it in a restaurant.Good butchers make their own and it's easy to cook. Haggis is all the scraps (heart etc and pearl barley)When put this into an intestine it comes alive.!!!! Their are some special ones that live on heather.You just have to pluck them and snip off the wings. Try battered mars bars or pizza and blacken your teeth so you fit in.
