Try scraping up the edge to see if it is paper/plastic or a metal plaque.
If it is paper/plastic you might try very carefully scraping up the whole thing then trying to read it in a mirror.
If it is metal try scraping paint over to a letter. If the letter is embossed scrape away. If it is printed with ink/paint of some sort you are left with the conundrum of deciding between chemical strippers or scraping.
