It may seem counter intuitive, but I'm not seeing a huge increase in value for these sort of boxed commeratives at this time. Most are put aside in safes and not used. Not a lot of Ruger Collectors at this time. It's all about supply and demand and the demand for safe queens for collectors just doesn't seem to me to be all that strong.
In other words, maybe a $100 to $200 premium over a normal Vaquero.
Seems to me to be more market for 'shooters' than for 'safe queens' at this time.
"Contender" says about $650 and I'd suggest maybe another $100 or so to $750 plus or minus $50 for the logo and box.
I have one of the late issued 'clean up' ones - warning under the barrel. Less than 100 made up with out the SDSD logo.
Less than 1,000 of the original run and maybe only 800 with the logos.
Just my $0.02 worth.
