Hello Don, your question seemed out of place in this thread. But I will comment upon it.
I have 18 old silver Mid-East coins with some dating back to 900 AD. My son was in Desert Storm and recovered them from a blown up house. Two appear to have been struck over with a Crusader Cross. They are really dirty and I have no idea what they say.
Are they worth anything.
The first thing that I noticed is that you have been around a bit here at TN as denoted by your profile. So, I'd think that you would have posted this question either in another thread that was more on topic or that you would have created your own thread for it. Secondly, I see that you already seem to know that (at least 'some') of these coins you are talking about date back to about 900 AD. Which leads me to believe that you have already talked to someone who knows something about these or this type of coin. Thus, perhaps, you are seeking a second opinion as to value.
Another thing that I note is that you should know (having been around) that like almost any other coin, condition is an important factor in determining value. Yet, you did not mention what condition these coins are in. Were they damaged in the explosion? I also noted that their size was not given, nor pictures (which is okay since this is really not the thread for this subject unless the reason for posting about that here is because you are wondering about sending them in for grading). Also, you say that they appear to be over-struck. That can be either a plus or a minus in terms of value, depending upon when and what they were over-struck with.
In general, coins of this type, in my experience, based upon grade, etc. would be worth about $20-$30 each in high grade. Note that I said "IF" in high grade (Unc. or better) and if NOT over-struck of the denomination of the size of 25 to 30 mm's in diameter. However, the market flucuates or changes for such coins. What I have said here is only a general value for the specific coins of the type which I have described.
The value could be better determined by those who specialize in that sort of coin and who know more about the current values and who know more about the coins that you have in terms of condition, denomination, etc. It sounds like we are talking about circulated coins. I see circulated coins of this type selling frequently at coin shows for about $5.00 to $10.00 each. This is just to give you a general idea as to potential value as this is what I think you were asking about. Best regards,
