Form 3520 after Foreign Inheritance increased in value over years and 2022 sale

Hello,

Father inherited half of a foreign property 20 years ago. Valued less than 100K at the time.

Sold his share in 2022 for slightly more than 100K.

Should Form 3520 be filed for tax year 2022?

Seems it should not have been filed for any previous years as value at time of inheritance was

under 100K. How do people deal with an inheritance 'increasing' in value regarding form 3520

over years?

Thank you.
