Where 174 fits
Why 174 is special
Using it for a mark that is not registered is an offence in several jurisdictions, which is not true of the trademark sign.

In historical numeral systems
Egyptian
1 coil of rope, 7 hobbles, 4 strokes
1 × 100 + 7 × 10 + 4 × 1 = 174. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 vertical wedges (sixties place), 5 corner wedges + 4 vertical wedges (units place)
2 × 60 + 54 = 174. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
rho, then omicron, then delta, marked as a numeral
rho-omicron-delta + keraia
rho + omicron + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
qof, then ayin, then dalet
qof-ayin-dalet
qof (100) + ayin (70) + dalet (4) = 174, written in descending order.
Maya
1 bar + 3 dots (upper, twenties place) over 2 bars + 4 dots (lower, units place)
8 × 20 + 14 = 174. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
