WANTED: Native American Indian arrowheads and artifacts (La Porte)

I've LOVED and collected authentic arrowheads and artifacts for over 40 years, since I was a teenager.
I've searched plowed fields in La Porte County for thousands of hours over the years.
It's getting harder and harder to find them, especially at my "elevated" age (63).
I'm looking to purchase REAL artifacts from the Northern Indiana area for my collection.
I'd even consider items from the Midwest.
I'm not a dealer.
I'm not looking to resell these for a profit.
If you have any that you'd like to sell, please give me a call.
Some people have a box or coffeecan of them laying around.
I'll pay a very fair price.
They don't have to be perfect, just real authentic Native American artifacts.
Thanks for your consideration! Please give me a call, or send an email, if you have some to sell.
Two-one-nine, three 6 two, 5 zero two one.
Thank you!
