I paid about $325 for mine, IIRC. That was some years (8-10) back though.
Folks seem to love the 452's and with them no longer being produced, I bet $450ish wouldn't be far off with some going higher on gunbroker.
Not even close. 452's are in very high demand And they don't make them anymore.
$400-450 It's what you could buy them for a few years back brand new. Can't touch them for that now.
