Depends on 3 things. Condition, condition, condition.
Around 60000 to 100000 dollars.
$850 which is the equivalent of $20,709 today.
It is worth what someone will pay for it. There were many different variations of the Model T built in 1922. If you have a rare one then it is worth more than a typical Model T. The value of your car can only be determined by an expert and even then it is only an estimate. A 2dr. coupe is worth around $16,000 in great condition were as a Runabout will be worth $20,000. If your car is indeed mint, it will be worth much more. Mint means just like brand new so do not use that term lightly.
Cost today? Depends on condition, condition, condition, and year.
In 1909 it cost $850 ($20,709 today's money) but by the 1920s the price had dropped to $290 ($3,575 today).[Although the above prices are not incorrect, they are for a 'touring' model. You could purchase a 'runabout' model of the 1909 model t for 825$ (19 764$ today) and, by 1925, purchase the same car for 260$ (3 205$ today).]
