Missed a Palindrome

Probability Level 1

A palindrome is a number (with no leading zeros) that remains the same when written backwards. For example, 303 and 242 are both palindromes, while 128 and 030 are not.

After hearing an interesting fact that the number of 3-digit palindromes is 90, Alice says, "For each of the 3-digit palindromes, we can add a single digit from 1 to 9 to both ends, so the number of 5-digit palindromes is 90×9=810.90 \times 9 = 810."

Then Bob disagrees and says, "That is incorrect, you missed some of the palindromes."

Which of the following can be a palindrome that Bob says Alice missed?
