An interesting observation I made on an Indus seal. Possible continuity of Indus script.

See this seal from Harappan civilization, you see a human figure confronting two tigers. Take a note on the symbol which is encircled in red.

Similar symbol occurs in later Indian coins of Janapadas and tribes. See this coin of Himalayan Kuninda tribe. You see same Indus symbol below the Swastika. This is dated to 1st century BCE.

Same symbol occurs in many other coins as well, see these coins from Kaushambi. You see same symbol as a standard in front of antelopes. This symbol is dubbed as Indradhvaja or standard of Indra used in festivals by numismatists. But exact identification of it remains unknown.

There are few other variants of this symbol occurring in many other coins. Some coins depicts the standard inside a sacred railing or Vedika like seen in this coin from Eran, suggesting it was a sacred object of worship.

All pics are taken from the internet, I own NONE of the images!
