| Quarter With Red Paint. |
Have you ever found a quarter that had red paint on it. I've found a few. I never paid much attention to them. K just figured that some kid decided to paint his change, but I just found out there could be a more interesting story behind the red quarters. Here is what I learned from an article I just found.
Firstly, let me point out that there are a few alternative origins that are possible – but, not as neat as the arcade connection. Red quarters are also used for free laundromats and the occasional jukebox at the local tavern,..
Red quarters are known as “shills” or “house coins.”...
When a customer complained about not receiving credit for their coin, an attendant would use a red-painted quarter in the slot to make the game work. If it did, the customer could then play their game and smile. If the game still did not work, an “Out of Order” sign would be placed over the screen until a repair technician could render first aid.
When it came time to count the game’s coin box each week, the red quarters would be sorted out from the silver ones and returned to the attendants to use again. They wouldn’t be counted as income, and the arcade owner’s accountant would celebrate and rejoice at the reduction of paperwork...
Here is the link for more of that article.

Isn't it nice how knowing more about something makes everything more interesting. A curious person is never bored but a dull person is often bored.

I received some answers to the mystery items I recently posted. First, this one.

DJ said this one reminded him of one of disc shaped padlocks used for more secure locations, such as the following one.

Next, this mystery item.

| Mystery Item Two. |
Mark G. said the following.
I think your right about the mystery object that looks like a bullet, it is a bullet but. Most bullets are lead with copper jackets this bullet is missing the lead because it was filled with tracer compound. My theory is it’s a tracer round, looks like a 50 caliber.
He added that the white could be paint since tracer bullets would be painted for identification.Thanks guys. Great answers.

Here is part of the abstract of a paper describing a couple deep-sea salvage and recovery systems.The recovery and salvage of objects involves accurately obtaining their underwater positions. Depending on whether or not the salvage object carries an acoustic beacon, two methods are available: onboard acoustic signal search and near-bottom sweep search and search. Once the underwater position of a salvage object is known, it can be recovered and salvaged with a remotely operated underwater vehicle (ROV) and/or human-occupied vehicle (HOV). However, there are many difficulties with the practical application of existing deep-sea recovery systems that are based on the deep-sea operation of ROVs and HOVs. Based on the design idea and working mode of TV-grab in oceanography, this paper proposes a new type of deep-sea recovery system that does not rely on operating underwater vehicles and presents its recovery process. The new deep-sea recovery system combines underwater optical imaging, mechanical docking/grasping, acoustic imaging and positioning, and propeller operating to provide low-cost and rapid deep-sea recovery. Compared to the deep-sea recovery system with a ROV and/or HOV, the new deep-sea recovery system without an operating underwater vehicle described in this paper is proposed to be used, but not tested yet.
Here is an illustration from the paper.
