Two things in that one sentence.....Firstly dealers have a differing degree of what's a VF coin and EF coin, so that`'s where you come in, you have to know your own onions in that respect. Spinks quoted prices, well, take those with a pinch of salt. Then there's pricing, this comes from varying factors, grade and rarity are 2 of the most important. You mentioned a George V Crown on this website, but never mentioned which or grade, you did mention Spink however, Spink is merely a guide, rarity has no guide, nor does high grade, plus rarity..
