Welcome and thanks for posting all the pictures.
I would agree the iridescence on your bottles is attractive and I would leave them as they are.
I am not seeing a whole lot of value in your late 19th century bottles - all are fairly common things. The Hostetter's Bitters is a common one - these get more interesting value-wise in odd colors, but plain amber I am afraid is simply very common. There may be a sleeper or two in the lot - bottles marked with town and state names from the southwest are of keen interest to collectors....
