I game this driver in 8* currently, so I have a lot of respect for it. These frequently go unsold on ebay for even $40. If there's a market for these it is very small.
Even the "newer" models circa 2011 and the black oxide version which was released later do not fetch much on the secondhand market. There are SO MANY DRIVERS out there newer with more flash, that it's tough to get anything.
I have a spare 8* original 919thi head myself. Thinking of getting a shaft in it and giving it away to a friend who is still playing a mid 90s "driver."
It's a fine club, but there's virtually no market for it. After shipping I think you'd be lucky to get $30.
