Yes, they are common but desirable too.
Value depends on condition, barrel length and finish.
A 4" blued with minor blueing wear (tip of barrel, sharp edges) $350 to $375 range.
Allot of wear or dings/scratches, about $300 to $325.
Like new, no wear, $400 to $450.
If 2" barrel, add $50.
If nickel, add about $50.
These prices are only approximate and my opinion, if sold privately. If sold to a gun shop, subtract $100.
Edit: It came with factory wood grips. If they've been replaced with rubber then subtract another $25 - $35.
