Hi All, New poster here, although I've been using the site for some time. and availing of the depth of knowledge and experience of the posters. I have come into a 1994 TAG HEUER 6000 SENNA. Its one of the first series, limited edition xxx/1000. Photo below, and link to description here: https://www.calibre11.com/ultimate-guide-ayrton-senna-tag-heuer-limited-edition/ I am wondering as a guide, how would one determine a price / value for what is a limited version of a mainstream watch? At the time they came to market - shortly after the death of Senna - they were impossible to get hold of. Currently there seem to be quite a few FS, but I have seen a great deal of variability on prices on-line. Many thanks in advance for any insight.
