You appear to have a Stanley Bailey No. 8 Jointer Plane (Type 9 or 10) dating
from about 1902 to 1909. Stanley made the plane but used Bailey's name for
better name recognition...
http://tooltrip.com/tooltrip9/stanley/stan-bpl/bailey-types.htm
Type 9: (1902 to 1907)
2 patent dates behind frog: MAR-25-02, AUG-19-02
‘Bailey’ at toe
straight frog rib
Type 10: (1907 to 1909)
Same as Type 9 except rib at frog seat is now arched
So you must remove the frog and examine the seat arch to narrow the exact
date range further.
As to value...it's complicated. Yours is from a desirable period when workmen
actually used planes, tuned them right, and generally took good care of them.
Yours looks about average: neither great nor bad. The rosewood handles
appear correct and are in decent shape. Handles must be tight with no slop
for best value. The blade and lever cap look usable. Can't tell more without
disassembly, checking the mouth, checking the sole for flatness, and making
some shavings.
There are so many details to evaluate. Are the all parts original to that plane?
It's common for wrong parts to be substituted and it's tough to tell all the
nuances in frog screws and depth adjustment forks. How much life is left in
the blade? Was the chip breaker buggered up by a tool butcher? Some light
surface rust is easily cleaned and doesn't detract from value. In contrast,
severe rust pitting, cracks, or weld/solder repairs drastically reduce value.
Perfect japanning increases the value a lot because it's so rare. Having the
original box is very rare. Those two together and you have a "New In Box"
plane which gets into crazy money for this period and earlier.
Only a real plane expert can answer these questions. From your photos it's at
least a $100 plane and a good, basic "user". It can easily work just as well as
any $475 Lie Nelson recreation. If all the parts are original and in good shape,
then you might indeed have a $180 plane.
As others have said, you can't use Ebay as a reference. Most Ebay sellers
bought a plane for $50 in a flea market, know nothing about planes, and are
just trying to flip it and quadruple their money. I often buy planes at flea
markets or on Craigslist for a fraction of the typical Ebay prices. Some planes
do sell for real market value on Ebay, but it's not common.
A better source for real market value are old tool dealers. Some dealers
have very high prices overall, but they're also carry only rare planes sought
by the wealthiest collectors. Or they may just be looking for suckers. In
contrast, Patrick Leach is a much better resource. His prices are very fair,
he's honest, and he keeps up with market value. Get on his mailing list
and watch his prices. He prices "user" planes and "collector" planes
accordingly, and both are in his monthly list. And he knows everything
possible regarding old Stanley planes...
