How much a letter from Michelangelo worth?

Question

Today I bought an original letter from Michelangelo to his father. It has an authentication raised stamp on it. I bought it from an antique store that was closing down. How much do you think it worth? Where can I go to find out the real value o it?

Answer 1

Methinks @MedGuru needs a massive transfusion of critical-thinking skills, stat.

Some random antique store sells you a supposedly priceless and unique manuscript by one of the most famous human beings who ever lived, and then conveniently goes out of business so you can't get your money back when it turns out to be fake. Riiiiiiiiiight.

Answer 2

If it's real? Hundreds of thousands of dollars. Maybe a million?

If its not real? Very little.

An authentication stamp probably isn't enough - you would have to get it verified by a specialist.
