<p>[QUOTE=&quot;physics-fan3.14, post: 3664932, member: 19165&quot;]The difficulty with putting accurate values on rare varieties is precisely because they are rare! If a variety only comes up to auction once every few years, it is very hard to put an accurate value on that. Looking at the Heritage archives is going to be your best bet, although there isn&#039;t really a formula. This R5 variety might go for quite a bit more than that R5, simply because two collectors both needed it at the same time and had a good fight over it.[/QUOTE]</p><p><br /></p>
