Something like a 5" Sick Fish, Money minnow, Swim-N-Shiner etc.

Probably anywhere from a 1/16 to 1/4 of an ounce based on size. I haven't weighed any but I'm holding a 5.5" shadalicious in one hand and a 1/4 oz. tungsten in the other and they feel about the same.

How fine do you want to get?  A decent electronic scale, one that will weigh down to + or - a gram or so doesn't cost that much.   I think I got mine from Walmart for around $25.  I would guess that  5" Money Minnow would weigh in the neighborhood of 16 to 20 grams, but I don't know for sure.   That is something for me to check out the next time I have spare time fooling around in my fishing shed.

I have a digital scale. Here are the results:

 

No hook - 3/8 ounce

With hook - 3/8 ounce

 

Would think different brands and styles will weigh different in addition to the weight of the hook, thin or heavy wire.

Just wondering w/o the hook, thank you.

looks like sam hit it right on the head with that response !!

5" Big Hammer is 1/2 oz. those others listed at 5" may not be as thick as a 5" Hammer so could be 3/8 - 1/2 oz I'd say..
