Gold Coin Grades 1907 $5/ 1925 $2.5

both seem to be AU pieces although the 1907 $5 might be an MS contender.

There is too much washout on the lighting to get a feel for the surface originality on the coins.

Keep in mind that gold is softer and will display characteristics on the surfaces that would be considered "damage" on their silver coin counter-parts; moral to the story being, don't let some surface dings discourage the value of the coin or its grade. However, with gold, you will see lots of cleaned specimens due to folks feeling the need to clean them with jeweler-type solutions over the course of time. Again, less lighting on these pics would help.

Both appear to be upper AU, at least 55 and possibly 58. It's darned near impossible to tell from these photos if they have ever been cleaned or dipped, so I'll pass on making any such pronouncement.

Both are mid-AU

I would agree with 55 on both, certainly no worse.
