Welcome, Wayne

If you use eBay or Craigslist as a measurement, Tiger prices are varied. Hemmings will exhibit the top-dollar cars.
Original does count for a lot with some crowds. A TAC certificate may also enhance the value on top of the originality.
I’ve seen anywhere from $10k to $85k, depending on the car and the condition. Its a tough market to gauge today.

To aid your judgement to which you may compare the asking price, here are some other similar cars have been recently available on the market:
