In order to get an answer here, you would need to describe the condition of the rifle. Unfortunately you haven't, So I am going to give you a Daisy web page that may to be able to help you if you want to pursue it.

Here is a list of Daisy that have the Eagle name in it. Model 98 Daisy Eagle made 1955-60 Model 98 Golden Eagle 1957 Model104 Golden Eagle 1966-74 Model 1776 Golden Eagle 1968-72 Model 50 Golden Eagle 1936-40 Which one is yours?
Daisy made at least three different rifles named "Golden Eagle," maybe more. My suggestion is to contact Daisy directly. Daisy offers a FREE service to tell you more about your old Daisy. (see the link below)
$2600
100-400 or so
Depending on condition, 150-500 USD.
It would be worth somewhere around $175 - $210 For the model 98 Eagle
From what I can find, it's worth around $400 in good cosmetic and working condition.

This simple question has a complex answer: First of all you didn't provide any information about the condition of the rifle. So I can not give you any estimate of value. The Current condition determines the value. Next. I could not find any information on a Daisy model 1405. I have several references. Then I remembered that Daisy and several other air gun companies made airguns for Montgomery Wards and Wards used crossover model numbers starting with 14??. I believe yours may be a Daisy model 98 golden eagle made between 1955-1960. You may want to search the web (photos ) and find a photo of a Daisy model 98 and see if it looks like yours. BTW the Montgomery / Daisy models are not as collectible as a regular Original Daisy models.
The Daisy model 104 Golden Eagle was made between 1966-74. It is nice that it is in very good working condition but I need to know what is the physical appearance of the rifle like. Is it also in Very Good appearance (No Rust. Cracks, Dings. Wear?) all this determines the value of the rifle.
If you mean a 1905 Liberty Head Double Eagle? As far as gold $20 coins go, this one is very common. Value is $1,780.00 to $2,100.00 depending on the grade of the coin.
as much as someone is willing to give you for it.
