That gun has appreciated _some_ over the years but not as much as you might think. Just a matter of inflation. My standard way of comparing prices it to use gold. Gold in 1955 was $35.15 an ounce. So it would have taken 2 and a quarter ounces of gold to buy that gun. Flash forward to now. Our sad little dollar..... it now takes $1200+ to buy an ounce of gold. So.... same 2.25 ounces of gold.... that's $3000+ in today's money.
