Bruce,
You will get a number of replies here, let me be the first. Welcome to the forum. The generally accepted serial range for test eagles is 6100 to 7100, but several on this board would give a broader range of 5800 to 7800 and consider it a potential test piece if it lacks the "Germany" stamp. The only pistols universally accepted as test pieces are those that are known to be from the Bannerman purchase from the US government in 1906. These include serials
6176-6196
6282
6361-7108
7147
One of the gentlemen who will chime in is Dwight Gruber. He has compiled an extensive listing of these pistols... See:

The placement of serials on the pistol would help in identification, and photos would be superb. As to value, depends on what you have and I will leave it to those who follow to speculate, but you will get the most accurate assessment by posting photos first. Again, welcome.
