First of all, welcome to the forum, IDigHistory!
My catalog (which by the way has a pic of it) gives the value in VG (lowest available there) condition of $20.
It doesn't say the silver content because, I suspect, it wasn't constant. The weight varied as well.
I'd say, IDigH, you should ask yourself whether the coin is worth $5 to you! If you find it attractive, as a numismatic and historic piece, and if shelling out a $5 not a very big deal, go for it. If you're interested in it as an investment or just for its silver content, then I'd look for a more secure deal.
