Well first off. Cameos and Deep Cameos (Dcam) are only on proof coins. Your coin is a business strike coin from Denver. What if the difference between a business strike and a proof strike. The proof coins are struck at least twice and on larger coins, sometimes even more. The second strike makes the devices stand out a lot more.

Note the condition on the proof strike? The fields are very mirror like. But this is not a cameo strike.
Why Not? Because the of missing frosting on the bust and the Memorial building.
The proof example on the right is a normal proof cent. The one on the left is a business strike coin.

Note the frosting on the bust. You see it slightly compared to the normal proof strike. But compare it to the Dcam on the next images.

So now you see that the cameo is stronger, thus the grade of Dcam.
On the older coins the frosting was only applied once when the die was being created. Thus only a few strike will show this cameo look on the bust and the Memorial building. Later on they kept adding the frosing to the die, so that the Dcams and Cameos are common to find. Thus the prices dropped a lot. You can get a PR-70 Dcam for so little of value that to have them graded pretty much exceeds the value for them today. Thus the older cameos have a higher price tag on them.

But today the prices are a lot less even on the high grades:

The grading fees would exceed the value of the coins.
But your coin is not a proof coin.
