Adventure Comics #51 worth

The Adventure Comics #51 (1940) is the only issue on the list with significant value, priced at $1,035 used. The rest are modern issues (#510–#519) from 2010 and are worth between $3.47 and $5.20 used — these are mass-produced modern comics and not rare. If you have the 1940 version, it’s a classic and worth the higher price, but if you have a 2010 issue, it’s a low-value comic. Check the cover date and condition to confirm.
