Do you have any scans of the autographs?

I agree with guilder1st on the Audrey Hepburn. Although if it's not dated you can't really prove what year it was signed.

Signed photo's for Audrey Hepburn are valued in most price guides upwards of $500,-
But seeing how yours dates from around 1955 and comes with some history it could probably sell for much more(depending on the quality of the Autograph).
I would insure it in the $1500,-/$2000,- range.

As for Tina Turner a signed record from that year should sell upwards of $300,-. Insurance value probably in the $500,- range.

I have no idea about the value of the HRH Charles Prince of Wales signed letter.

Hi everyone I'm new to the board so seasonal greetings from Spain....

I have several genuine autographs and I am not sure what value to place on them for insurance, so I am hoping you can all help I will list them as best as I can......

The first one is a handwritten letter by HRH Charles Prince of Wales and is on Highgrove Official Paper, it is thanking his staff for the wonderful present of a garden bench he received for his 40th birthday its on two sides of A4 Paper hes signed it at the end,, Your agening Employer Charles

The second one I have is Audrey Hepburn 10 x 8 black and white hand signed it was given to a carpenter and his wife at studios in hollywood at around 1955 its signed in blue ink.

The third item I have I need to get valued is a single record of Tina Turner I dont wanna loose you, The cover is signed by Tian and was signed at the MTV awards when the record was released


Hope you can all help and I look forward to posting many times in the future.
