Okay, using 2.1cm and 2.8cm I still have no idea how you're getting your volume from. Even very roughly approximating the egg to a cuboid 2.1 × 2.1 × 2.8, the egg would be under 12.5 cubic cm. In reality, it's probably about half that, closer to 6 cm3, ~120g.
But yes. Still good money. $6-7k per nug.
Edit: I think 49.42 came about by taking (2.1×2)^(2) = 17.64 ('rounding' to 17.65) and multiplying by 2.8 to get 49.42. But 2.1 is width, not radius, so there's no need to double it.
Anyway another commenter helpfully provided a formula for egg volume, and a(n American) robin's egg comes to about 7cm^(3).

"The resulting formula for egg volume, V, was V = (0.6057 - 0.0018B)LB2 in which L is the egg length in millimeters, and B is the egg maximum breadth in millimeters."

Thanks for the formula. It's for chickens, but works well for an estimate. Using that formula, we get 7012.429 mm^(3), or 7cm^(3) for an American Robin egg, still nowhere close to 49.
European Robins lay smaller (non-blue) eggs, 2cm long and 1.5cm wide with a volume of ~2.6cm^(3). That would be about USD2.7k worth of gold.

From here is where I got the formula. https://sciencing.com/calculate-volume-egg-7892704.html
Or you can use this. https://goodcalculators.com/egg-surface-area-and-volume-calculator/

If you'd used that you would have obtained:
2/3•pi•R•R•(L + S) = 2/3•pi•(1.05)•(1.05)•(2.8) = 6.47
